The surface area of a square pyramid can be calculated using the formula:

Surface Area = Base Area + (1/2) * Perimeter of Base * Slant Height

Given that the base of the pyramid is a square with a side length of 9.9 ft and the slant height is 15 ft, we can calculate the surface area as follows:

Base Area = side^2 = (9.9)^2 = 98.01 ft^2
Perimeter of Base = 4 * side = 4 * 9.9 = 39.6 ft

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. None of the provided answer choices match this result, so please recheck the calculations.
