surface area of a pyramid

The surface area of a pyramid is equivalent to the sum of the faces of the pyramid

For the given square pyramid;

TSA = (5*5) + 4(1/2 * 9 * 5)

Simplify to have;

Surface area =25 + 4(45/2)

Surface area = 25 + 180/2

Surface area = 25. + 90

Surface area = 115 square inches

Hence the surface area of the square prism is 115 square inches
