To find the surface area of a square pyramid, you need to calculate the area of the base and the area of the four triangular faces and add them up.

First, calculate the area of the base:
Base area = (side length)^2 = 8^2 = 64 ft^2

Next, calculate the area of each triangular face:
Triangle area = (1/2) * base * height
Triangle area = (1/2) * 8 * 16 = 64 ft^2

Since there are four triangular faces, the total area of the triangular faces is:
Total triangular faces area = 4 * 64 = 256 ft^2

Finally, add the base area and the total triangular faces area to find the total surface area:
Surface area = Base area + Total triangular faces area
Surface area = 64 + 256 = 320 ft^2

Therefore, the surface area of the square pyramid is 320 ft².
