The height of a side on a pyramid is 11 inches long, and its square base has sides that are 6 inches long. What is the surface area? 233 in. 2 168 in. 2 144 in. 2

To find the surface area you can Think of the net that is created from a square pyramid.

The net will consist of four congruent triangles and one square base.

The area of the base is 6 inches times 6 inches or 36 in.².

The area of each lateral face (triangle) is 6*11:2 or 33 in.².

33 in.² x 4+36 in.² = 168 in.².

The surface area is 168 in.².
