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

Answer:

The height of the pyramid is $1.875\ cm$

Step-by-step 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

$240=(128)h$

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