Define the formula for the surface area of a square pyramid. A square pyramid has a square base and four triangular sides. The formula for this case is: A = s ^ 2 + 2 * s * L Where, s: side of the base L: inclined height The inclined height is: L = root (h ^ 2 + (s / 2) ^ 2) Where, L = root (12 ^ 2 + (12/2) ^ 2) L = root (144 + 36) L = root (180) L = 13.42 Substituting values: A = (12) ^ 2 + 2 * (12) * (13.42) A = 466.08 in ^ 2 Answer: The surface area is: A = 466.08 in ^ 2
