You're given :
`The volume of a cylinder is 81 ft3.`

ganeshie8 · Answer

volume of a cone that fits exactly inside the cylinder wud be 1/3 rd of the volume of cylinder

ganeshie8 · Answer

So volume of cone = ?

anonymous · Answer

the volume of the cone would be 27

ganeshie8 · Answer

Excellent !

ganeshie8 · Answer

use the same trick to find the volume of pyramid also

anonymous · Answer

would it also be 1/3?

ganeshie8 · Answer

You're given :
`The volume of a cube is 42 ft3.`

volume of pyramid that fits exactly inside this cube  = ?

ganeshie8 · Answer

Yep !

anonymous · Answer

so the pyramid would be 14?

anonymous · Answer

that fits in the cube

ganeshie8 · Answer

Correct !

`What is the difference between the volume of a cone that fits exactly inside the cylinder and the volume of a pyramid that fits exactly inside the cube?`

anonymous · Answer

i just subtract the cone from the cylinder and the pyrimid from the cube

ganeshie8 · Answer

nope, you just subtract `cone and pyramid`

ganeshie8 · Answer

volume of cone = 27
volume of pyramid = 14

difference = ?

anonymous · Answer

13

ganeshie8 · Answer

thats it !

anonymous · Answer

and the volume of a pyramid that fits exactly inside the cube? << whats that mean though. that makes it sound like you get the difference there too

ganeshie8 · Answer

the volume of a pyramid that fits exactly inside the cube   =  42/3 = 14
