This document discusses calculating the surface area of prisms and cylinders. It provides formulas for finding the lateral area and total surface area of prisms and cylinders. For prisms, the lateral area is calculated as the perimeter times the height, and the total surface area adds the lateral area and twice the area of the bases. For cylinders, the lateral area uses the circumference times the height, and the total surface area adds the lateral area and twice the area of the circular bases. Examples are provided to demonstrate calculating the lateral and total surface areas of specific prisms and cylinders.
