To solve for the surface area of a square pyramid, you can use the formula:
Surface Area = base area + (1/2) * perimeter of base * slant height
First, calculate the base area of the square pyramid:
Base Area = side length^2 = 9.9^2 = 98.01 ft^2
Next, calculate the perimeter of the base:
Perimeter of base = 4 * side length = 4 * 9.9 = 39.6 ft
Given the slant height is 15 ft, plug the values into the formula:
Surface Area = 98.01 + (1/2) * 39.6 * 15
Surface Area = 98.01 + 297
Surface Area = 395.01 ft^2
Therefore, the surface area of the square pyramid is 395.01 ft^2.
