The Great Pyramid at Giza, Egypt, is 147 meters tall, and each side of the base is 240 meters long. What is its volume?
The formula for the volume of a pyramid is V = (1/3)·(Area of the Base)·(Height)
Since the base of the pyramid is a square, 240 meters on each side, the area of the base is:
A = 240 m x 240 m = 57,600 square meters
The volume of the pyramid is: V = (1/3)·(57,600 m2)·(147 m) = 2,822,400 m3.
