Best ResponseYou've already chosen the best response.1The formula for the surface area of a regular square pyramid is this: SA = B + 1/2 * p * L where B is the area of the square base, p is the perimeter of the square base, and L is the slant height of the pyramid.

Best ResponseYou've already chosen the best response.1Find the slant height of the regular pyramid. It is the height of one of the triangular faces of the pyramid. Slant height is not the same as the height of the pyramid.
