1. Surface Area By: Alyssa, Remy, and Seth

2. Definition Surface Area is the measure of the outside of a three- dimensional figure.

3. Formulas for finding Surface Area Prism- SA= Ph=2B Cylinder- SA= 2x3.14rh+ 2x3.14r^2 Cone- SA 3.14rsh+ 3.14r^2 Square Pyramid- SA= 1/2Psh+ B Sphere- SA= 4x3.14r^2

4. Example 1 SA= Ph + 2B SA= 9x11 + 2x12 SA= 123 prism

5. Example 2 Sphere SA= 4x3.14r^2 SA= 4x3.14x2^2 SA= 50.24

6. Practice 1. The Perimeter of the base of a square pyramid is 40 millimeters and the surface area of the pyramid is 358 square millimeters. What is the slant height of the square pyramid? SA= ½ Pl+B 2. what is the surface area of the following prism?
