Use a net to find the surface area of the square pyramid.

208

Step-by-step explanation:

Base:8x8=64

8x9x4divided by 2=8x9x2=144

208 feet^2

Step-by-step explanation:

This figure has four triangular sides and a square bottom.  Given that the length of one side of the square base is 8 feet and the slant height 9 feet, we apply the area-of-a-triangle formula A = (1/2)(base)(height) to find the area of one side:  A = (1/2)(8 feet)(9 feet) = 36 feet^2.

Since there are four sides, we multiply this result by 4, obtaining the total surface area of the sides:  144 feet^2.

Finally, we calculate and add the area of the base, which is (8 feet)^2, or 64 feet^2.

The total surface area of this square pyramid is thus 144 feet^2 + 64 feet^2, or 208 feet^2.
