To solve for the surface area of a square pyramid, we use the formula:
Surface Area = Base Area + (0.5 * Perimeter of Base * Slant Height)
First, let's find the base area of the square pyramid:
Base Area = side^2 = 9.9 ft * 9.9 ft = 98.01 ft^2
Now, let's find the perimeter of the base:
Perimeter of Base = 4 * side = 4 * 9.9 ft = 39.6 ft
Given slant height = 15 ft, we can now plug all the values into the formula:
Surface Area = 98.01 ft^2 + (0.5 * 39.6 ft * 15 ft)
Surface Area = 98.01 ft^2 + 297 ft^2
Surface Area = 395.01 ft^2
Therefore, the surface area of the square pyramid is 395.01 ft^2.
