The document discusses calculating the surface area of prisms and cylinders. The surface area of a prism is the sum of the area of its polygon base, the area of its lateral faces, and the area of its other base. The surface area of a cylinder is the sum of the area of its circular base, the area of its lateral surface, and the area of its other circular base. The document provides formulas to calculate the surface area of prisms and cylinders and examples of problems to solve.

1. Basic Geometry Unit 11.4 – Surface Area of Prisms and Cylinders

2. Surface Area The amount of material it would take to cover a geometric solid is called the surface area . If you “unfold” a geometric figure, the result is a net .

3. Surface Area of a Prism: SA = Ph + 2B B is the Area of the Polygon Base h is the height of the prism P is the perimeter of the polygon h B B B h P

4. Surface of a Cylinder: SA = 2 π rh + 2 π r 2 π r 2 is the area of the Circle Base h B B B h C h is the height of the cylinder 2π r is the circumference of the Circle Base

5. Find the surface area of each solid. 16 cm 8 cm 25 cm 14 ft. 7 ft.
