If the base length is 6 inches then the base area will be 9*sqrt(3) = 15.6 cm2, which rounds to 16, not 15. So some of the information provided is patently incorrect and therefore the question has no sensible answer.
It is 36 cubic inches.
To calculate the surface area of a square pyramid, you need to find the area of the base (which is a square) and the area of the four triangular faces. The formula for the surface area of a square pyramid is SA = s^2 + 2sl, where s is the side length of the base and l is the slant height. In this case, with a base side length of 8 inches and a slant height of 15 inches, the surface area would be SA = 8^2 + 2(8)(15) = 64 + 240 = 304 square inches.
