One of the ancient stone pyramids in Egypt has a square base that measures 143 m on each side. The height is 105 m. What is the volume of the pyramid?

To find the volume of the pyramid, we need to multiply the area of the base by the height and divide by 3.

The area of the square base is calculated by multiplying the length of one side by itself: 143 m * 143 m = <<143*143=20449>>20449 m^2.

The volume of the pyramid is calculated as follows: (20449 m^2 * 105 m) / 3 = 2156595 m^3.

Therefore, the volume of the pyramid is 2156595 cubic meters.
