Answer:

Volume of pyramid = 5000 cubic inches.

Explanation:

Given the following data;

Length = 20 inches

Width = 30 inches

Height = 25 inches

To find the volume of pyramid;

Mathematically, the volume of a pyramid is given by the formula;


Volume = \frac {1}{3} * base \; area * height

First of all, we would determine the base area;

Base area = length * width

Base area = 20 * 30

Base area = 600 in²

Substituting into the formula, we have;


Volume = \frac {1}{3} * 600 * 25


Volume = 200 * 25

Volume of pyramid = 5000 cubic inches.
