Question

a soild right pyramid has a square base with an edge length of x cm and a height of y cm. which expression represents the volume of the pyramid

Answer 1

The volume of the pyramid is
`V=(1)/(3)(x^(2))(y)\ cm^(3)`

Explanation:

we know that

The volume of the pyramid is equal to

`V=(1)/(3)BH`

where

B is the area of the base

H is the height of pyramid

we know that

The area of the base is

`B=x^(2)\ cm^(2)`

The height is equal to

`H=y\ cm`

substitute

`V=(1)/(3)(x^(2))(y)\ cm^(3)`
