Question

A square pyramid with a edge of 40 and a volume of 8000, what is the height

Answer 1

the height is 15

Explanation:

`(1)/(3)b^2h` is the formula to finding the volume of a pyramid

v = volume

v =
`(1)/(3)(40)^2h`

volume = 8000

`8000=(1)/(3)(1600)h`

Multiply
`(1)/(3)` by 1600

`8000=(1600)/(3)h`

Multiply both sides by 3

`24000=1600h`

Divide both sides by 1600

`h=(24000)/(1600)`

`h=15`

the height of the square pyramid is 15
