Lesson 7-7 Surface Area of Prisms and Cylinders

Definition Surface Area- The sum of the area of all the faces of a solid.

Formulas Surface Area of a Rectangular Prism- The surface area S of a rectangular prism with length l, width w, and height h is the sum of the areas of the faces. S = 2lw + 2lh + 2wh Surface Area of a Cylinder- The surface area S of a cylinder with height h and radius r is the area of the two bases plus the area of the curved surface.
