For a complete lesson on volume of a pyramid, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that the formula for the volume of a prism is length times width times height, so the volume of a prism that has a length of 25 inches, a width of 4 inches, and a height of 9 inches, is 25 times 4 times 9, or 900 cubic inches. Students also learn that the formula for the volume of a cube is side length cubed, and the formula for the volume of a pyramid is 1/3 times the area of the base times the height of the pyramid. Students are then asked to find the volume of prisms, cubes, and pyramids.

  • @36imfat If you guys/girls are confused as to what 1/3 is, it is a fraction, this cunt could have saved 1.5 minutes of ur life if she just said, B x H / 3 ( Divide by 3 ). And you are done.

  • oh god if school was straight to the fucking point without any bullshit, I would have saved 10 years of my life.

  • @nanopakour aw shut up! It's a good video.

  • Help me someone, how do you figue out the base of a pyramid when all you know is the height and volume?? And it doesnt specify what kind of pyramid it is

  • 1/3 mean???

    

  • here accent makes me angry, its just so annoying!

  • @kohistaniification oh my gosh thank you sooo much !!!

  • @MisslaylasCOOL your supposed to turn the fraction into a decimal and you do that by dividing the top number from the bottom (numerator divided by denominator) so it would be 5.25 x 5 x o.333333333333 = 8.75 good luck on ur big exam ;)

  • I dont get the 1/3 bit when i try do it on my calculator it just turns the whole thing into a fraction >.< HEEELP ! big exam soon :/
