Explain how you could calculate the surface area of a square pyramid.

Sample Response: You would first calculate the area of the base, which is length times width. You would then calculate the area of the faces, which is 1/2 (base times height) and multiply the result by 4 for the 4 faces. Finally, add the area of the base and the areas of the faces.
