Answer:
Step-by-step 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.
