A Maths Puzzle: The Missing Square Solution

[conman639]

It's a Cheez-it!

[TheDBest1994]

I was right as well @TadaKiba, I knew that the area was like a rectangle more and I knew the area was increased. I just didn't seem to know how it came to be 50 cubic centimeters.

[LosDynasty]

Now i can die in peace

[TadaKiba]

Yay, I was right!

[Contherage]

That's pretty fucking neat. No lie..

[MrD3STR03R]

Thank you :)

[beng115]

fucking love you SB!



[Dragononxtc]

when you said the area of the new shape is 50 units squared and that explains the 49 squares and the 1 in the middle, it's still 49 squares including the middle.i don't understand what you were referring to.

[yamxa996]

@Dragononxtc There are only 49 SQUARES, but theres a wide rectangle in the bottom that has the value of 1 square unit. So there is 50 SQUARE UNITS. I hope that explains it a little bit...

[naradia95]

I don't see why people have a need of proving themselves. There's no need to post kadahj2's answer. If you got it, good, but you're basically giving the answer away for others who want to try it.

[MrUlug89]

i told you few second ago on your other video =)

[PyhaMikrofoni]

quite brilliant

[boingyfly007]

I didn't actually know this puzzle had a solution on youtube.

[GiaIsTheBest]

You are awesome

[Austin101123]

Ericsurf6 is awesome! Definetely the best guy on youtube!

[xxoxxkellyxxoxx]

1:33 Nice and Flush.

[islandbuoy4]

this comment is a p.s. to my last one 7x7=49 plus a missing square? Hey moSeS could only OPEN 49 GATES. He obviously had not seen this video. The 50th was a bit of puzzle for the fella who talked to god? The Hindu use 50 letters is another CLUE. Chapter 49 of Genesis is another. why? All of the above is about tweaking your DNA with SOUNDs Because why? GENESIS is a GENEtheSIS IT IS TIME to choose a new VECTOR, a new direction for humanity, come 2012 These magic squares will help us!? namaste

[sktbrdr87]

I just looked at it and im like, red rectangle is interfering with the pink "l" vertical path. the gap on the yellow paper was at first filled in by the pink, but since the red is there, it is one unit up. I wrote this before I watched the spoiler so yeah.

[LordSaradoc]

You don't have to guess to solve it.

a = numbers of cows of cowboy A

b = numbers of cows of cowboy B

a+1 = 2(b-1)

b+1 = a-1

=>

a = 7 and b = 5

[motn2017]

you explained it in math, which was right, but in real what we did is changing the pieces and that should make differant space between the pieces so the pieces cant cover another area

[michaelsan010]

daming bobo amf. kitang kita nman na sobra tlga e, laos na to, daming bobo

[2020giu]

Just fantastic keep the good work :D

[superjeff14]

I paused it at 7 seconds in and am going to guess how it's done. If it's a 7 by 7 square now, you must turn it into a 6 by 8 rectangle so that the area is one less square. It works because a square will have the optimized area for a quadraliteral, and a rectangle isnt as optimized.

We just had an optimization test in calc today so it looks familiar. :D

Hope i get it right.

[jonlin1000]

this is called a paradox, which makes sense, but doesn't make sense at the same time. Confusing, huh?

[MrJohnniezzz]

@jonlin1000 how is it a paradox?

[LuvCatz905]

OMG my teacher showed me this today and I WAS REALLY IMPRESSED!!!!!

[SteelKristina]

so theres no ninja or pirate :(((((((((((((((((

[andyandy1020]

You are so smart.

[BluePi1313]

I don't know why i'm that stupid. I should've known this from the start.

[KouReaC]

in the centah'

[Spongebobvideopants]

hey is ur "Thanks for watching" is a catchprase?

[MegaRadarBoy]

he got a smaller matt and non of it is missing

[bartfstorm]

I mean a = 7 and b = 5

[bartfstorm]

@kedahj2

Cowboy a = 5 cows

Cowboy b = 7 cows

[NoRefundsXD]

i knew it

[mujijibu]

ericsurf6 :)

[MrRedeyedJedi]

thanks, how interesting.. I'm more of the scientifical types lol.. it's just a pitty that the majority of views are accounted for on stupid vidoe's like people getting hurt and things.. these interlectual puzzles and theories/workings, so it seems, are indeed un looked at quintisentially.. what does that say? well its not exactly evidence for anything.. just saying (i watch FUNNY stuff too lol.. only human) but im glad people post things like this on here.. good effort. :) 5 stars.

[garvito101]

Is that exactly 7 x 7 and 1/7th?

[singingbanana]

It is. The gradient of the slope is 2/7. The blue piece is 3 units wide, so the gap you see when I put the grid on top is an extra height of 1/7 units.

[greatvids4321]

@singingbanana

wait .. so you are saying that the extra pieces of paper that fall outside the 7x7 space is the missing area in the center ?

that is very cool.

is there also some crazy formula to solve this or does it just come down to good old logic?

[atlasvishnu]

try out my channel and if you like do subscribe .. thanks

[rasikpoudyal]

cool. i like this

[LordStean]

Fantastic! I have seen puzzles like this before, and was always wondering how it was possible, although i haven't gave it to much thought. Well done

[dgarci14]

ericsurf6 is awesome! everyone who likes puzzles and tricks should check him out and subscribe. "get some!"

[kadahj2]

heres an easy one: cowboy A ask cowboy B to give him 1 of hes cows so he can have double as cowboy B, but cowboy B tells cowboy A to give him 1 of his cows so they both have the same. How many cows does each cowboy have?

[vs5799]

whats the answer?

[thepianoaddict]

the answer is that its not a perfect square anymore. its a rectangle.

[singingbanana]

Very good, shall I leave it for others to work out?

[RodDuncan]

Another very enjoyable puzzle, thank you. I got this one, which makes it even more pleasing. :-)

[cageavvi]

@singingbanana 1

[minhboi2]

@singingbanana 5 and 7?

[orion285]

a7 b5 to start with.

[vs5799]

haha welldone

[Olaf177]

@kadahj2 wow thats nice

can u tell me in a private message?

[duhskills129]

@kadahj2 The answer: cowboy A =7 cows, cowboy b =5 cows

for:

7+1,5-1 = 8,4 8/4 =2

5+1,7-1 = 6,6

therefore Cowboy A = 7, cowboy b =5. That was an easy one

[coreysbrodylan]

@kadahj2 1

[albinrhinnooable]

@kadahj2 don't they both have 0 cows?

[TheMapleFans]

@kadahj2 Its 7 for cowboy a and 5 for cowboy B

[spazdaMX5]

@kadahj2 5 for a and 7 for b?=) gd puzzle!

[PencilStudios]

@spazdaMX5 no your wrong... 5 for a and 7 for b would mean that if b gave 1 for a they would both have 6... cowboy a wanted the double of b

[spazdaMX5]

@PencilStudios I meant 7 for a and 5 for b =/ sorry ty for the correction

[fspopshovit]

@kadahj2 Cowboy A has 3 cows, and Cowboy B has 2 cows. Is that right?

[vssnfrankiej]

@fspopshovit no because when cowboy b gives cowboy a 1 cow, A will have 4 cows and B only 1.

the answer is A has 7 and B has 5.

if B gives 1 cow to A, A has 8 and B has 4(2x4=8)

and when a gives B 1 cow they will both have 6

[fearfrozen75]

@kadahj2 is it 3

[Chesteryoshka]

@kadahj2 they have 3 cow each, but 2 of their cows belong to 2 cowboys?

my english sux =(

[ZOMGxTAKEDOWN]

@kadahj2 the 2 numbers have 2 gap differance so when cowboy A gives 1 of his cows to B they have the same and the numbers have to be below 10 bcoz.... I'm not gonna explain it the answers A=7 B=5 in 12secs :-)

[ChewyCheddar]

@kadahj2 Cowboy A = 7, Cowboy B = 5

[OpFlaVi]

@kadahj2 well after 2 minutes i solved it.piece of cake. cowboy A has 7 cows, cowboy B has 5 cows.cowboy A ask cowboy B for 1 cow so he can have double,7+1=8cows for cowboy A if B gave him a cow and B 5-1that hew gave A=4.8 is double as 4.now if A gave 1 cow to B there would be A 7-1 that he gave B =6 and B 5+1 that he took from A=6

[MEXICO579AC]

@kadahj2 5 & 7 :)

[LudicrousPlatypus]

@kadahj2 do you mean double the amount Cowboy B will have after he gives one cow, or before he gives one cow?

[Rockwarrior2004]

@kadahj2

A= 7

B= 5

[Parthematics]

@kadahj2 cowboy a has 7 cows and cowboy b has 5

[bryanturtle]

@kadahj2 is this problem unsolvable

[cowan913]

thanks so muck now i finialy no how it done

[garachomper737]

i TOTALLY knew that lol

that is so cool!

[JameseroseStudios]

Thanks, Very clear!

[Slowergrass432]

I love your brittisch accent :D

[dragson1234]

@Slowergrass432 I hate it when people get that wrong, now you being from the Netherlands and all you may not know, but there is no such ting as a British accent, Just like there's no specific American accent, it depends what part of the country you are from.

[Slowergrass432]

@dragson1234 so... then what accent is it?

[dragson1234]

@Slowergrass432 It's a Cambridge accent, i'm from England andI don't talk like that.

[singingbanana]

@dragson1234 *Nottingham accent.

[dragson1234]

@singingbanana Sorry! I had just read where you are from so Cambridge was stuck in my head

[ThePearI]

@dragson1234 It's an awesome accent really, or so I think.

[darkdudironaji]

@dragson1234 If your from England doesn't that mean you, technically, don't have an accent?

[dragson1234]

@darkdudironaji Why would that be? Everybody has an accent.

[darkdudironaji]

@dragson1234 Well England is where english came from. So don't you speak it properly and everyone except the english have an accent?

[dragson1234]

@darkdudironaji Well, I guess you could say that, but not everybody from England speaks the same. But an accent isn't about the language, it's about the pronunciation, and people pronounce things different.

[darkdudironaji]

@dragson1234 i guess that makes sense. I just thought everyone from there spoke the same.

[okuma0kuma]

every one else was posting equations my answer was simple it was rectangle not a square ,~insert smug expression here~

[MrSnipes911]

Thank you for the explantion, my braian is still in contact

[ericsurf6]

I've been using this puzzle for while and it always gets good response.

Wonderful explanation!

Couldn't remember if I did a video on it or not....

Thanks for the shout-out.....

[TyYann]

Nice and clear explanation!

[singingbanana]

Thanks Yann. I know the puzzles you were talking about before, using Fibonnacci numbers. I prefer this version, but that's just my opinion (it would be a way to teach Fibonnaci and the golden ratio).

[dave597]

nice! the transparent grid helps a lot! :)

[singingbanana]

Thanks. I was pleased with my transparent grid bit.

[Yesitis808]

Bloody brilliant.

[Seigge]

Right after u used the transparency and re-arranged the pieces u realize it more. Nice clever puzzle.

[rammstein812]

ahh i really was wondering how it could happen, still amazing tho, thanks for the awesome video

[hi1hi2hi2]

I was going to say on the last video that the square got bigger but i thought i was wrong so i didnt post, but still really nice puzzle =) gj

[Complexxx123]

can you make a video explaining what sin cos and tan mean when trying to solve a triangle sure i can push the button on the calculator but what do they actually mean???

[hi1hi2hi2]

Yeah im taking trig this year and i would like to know this too =]

[Begeru]

@Complexxx123 Do you know what the opposite, adjacent, and hypotenuse sides of a right triangle mean? If you understand those than you should probably know what the trig functions mean.

[michaelsan010]

@Begeru small brain. ewww

[rockbanddan]

@Complexxx123 They're all parts of trigonometry, the math of triangles. They stand for sine, cosine, and tangent. I forget what they all mean, but they have to do with the hypotenuse and the two other sides of the triangle. For example, one of the sin, cos, or tan might be the hypotenuse, C, over the length of a different side, A, when the triangle is isosceles, C/A, might be the tangent, but I forget what they really are.

[michaelsan010]

@rockbanddan small brain...ewww



[rockbanddan]

@michaelsan010 Small brain? Yeah, ok, bigger than yours. And P.S. if you're gonna say someone has a small brain, you should at least say it with correct grammar.

[michaelsan010]

@Complexxx123 small brain, simple math

[imlan123]

This annoyed the hell out of me :P

[Everything96]

wow! I like it!!

[pinkgirly222]

awesome!! Thanks for solution! :)

[Ilopsen]

Ah, that's it!

[Makaraka222]

I thought it was something like that :)

[omaristheman]

nice!
