Question

Determine the amount of stone needed to build one of the pyramids with a height of 145 m and a square base with a side length of 230m? Find the volume.

Answer 1

Explanation:

We would apply the formula for determining the volume of a square based pyramid which is expressed as

Volume = 1/3 × base area × height

From the information given,

Side length = 230m

Height = 145m

Since the base is a square,

Base area = 230² = 52900

Therefore,

Volume = 1/3 × 52900 × 145

Volume = 2556833.3 cubic meters

The amount of stone needed is expressed in volume.
