The volume of a square pyramid is calculated using the formula V = (1/3) * B * h, where B is the area of the base and h is the height of the pyramid.

Assuming the base of the pyramid is a square with side length 8 feet and the height of the pyramid is 40 feet, the volume can be calculated as follows:

B = (8 ft) * (8 ft) = 64 ft^2
V = (1/3) * 64 ft^2 * 40 ft = 853.3 ft^3

Therefore, the volume of the square pyramid is 85.3 ft^3 to the nearest tenth.

The correct answer is:

85.3 ft3
