One of the ancient stone pyramids in Egypt has a square base that measures 144 m on each side. The height is 87 m. What is the volume of the pyramid?
The volume of a pyramid can be found using the formula: V = (1/3) * base area * height.
First, we need to find the base area. Since the base is square, the formula for finding the area of a square is: base area = side length^2.
Given that the side length of the base is 144 m, the base area is:
base area = 144^2 = 20736 square meters.
Using the formula for the volume of a pyramid, with the base area of 20736 m^2 and the height of 87 m:
V = (1/3) * 20736 * 87
V = 604,608 cubic meters.
Thus, the volume of the pyramid is 604,608 cubic meters.
