Answer 1

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
