To find the volume of a square pyramid, you can use the formula V = (1/3)Bh, where V is the volume, B is the area of the base, and h is the height of the pyramid.
In this case, the base of the square pyramid is a square, so the area of the base is given by B = s^2, where s is the length of the base edge.
Given that the base edge is 40 cm, the area of the base is B = 40^2 = 1600 cm^2.
The height of the pyramid is given by h = slant height - apothem. However, the apothem is not given in this question. Therefore, we cannot find the exact volume.
As a result, none of the given options (533.3 cm^3, 8,000 cm^3, 12,000 cm^3, 24,000 cm^3) can be the correct volume for the square pyramid with the given dimensions.
