Question

A trapezoid pyramid has a base area of 128 square centimeters. If it’s volume is 10,240 cubic centimeters, what is the height of the pyramid

Answer 1

The height of the pyramid is
`1.875\ cm`

Explanation:

we know that

The volume of the trapezoid pyramid is equal to

`V=Bh`

where

B is the area of the trapezoid base

h is the height of the pyramid

we have

`B=128\ cm^(2)`

`V=240\ cm^(3)`

substitute and solve for h

`240=(128)h`

`h=240/(128)=1.875\ cm`
