Math Help with Suface Area

[karlferrer7]

where did u get the 4??

[otavioserenoo]

easy.. ridiculous

[rockinprincess345]

this is very helpful but numba 3 is HARD i reallin don't like math!!!!!!!!!! :P

[lrchang]

HOw do you find the surface area of a pyramid?

[silverhedgehog777]

Number 1&2 are easy 3 is confusing.

[dumont156]

how is the surface area 4 how did u get 4 for the sphere? som1 plz help i dont get math

[SandJDavies]

I get this stuff already! But isn't there a video that shows you how to work with the same thing but instead of using numbers, you're using variables? Like r = 2h h = h And work it out without numbers?? T^T I hate math.....

[LuaniCakes]

thank you!

[XSuperFistX]

i'd rate this vid 10 stars if i could

the lesson teaches surface area so frickin easy

[smartkitty991]

That's not the way I do IT at my school. I learn those formulas differently. In that it's SA=2(areaof base)+(perimeter of base)x height. I think I'll still with that way rather than his.

Ah thank you this explains alot, but for the cylinder 2ft is a bad example because it took me a while and i tried (pi r squared) and got the same answer but it doesnt if u use other numbers(Thats what confused me)...

You should also show how to work out the surface area of a pyramid

[klaburn09]

ok...i didnt get it

[ODBastardW]

the numeric answer is not the point, what i`m interested is the formulas which take us to those answers. good uploads anyway 10x . i rate 5/5

[brayrrero]

now i know and knowing is half the battle

Two of you are wrong. The title doesn't say you have to find the solid/volume because the title says find the surface area only. You have to find another mathematical lesson video from him.

[nycsharkman]

What about volume word problems?

What about high school solids?

[nycsharkman]

What about other math questions dealing with solids? How about volume word problems?
