1 Surface Area of Prisms

2 Lesson Objective Students will work with a formula for the surface area of a prism.

3 Lesson Beginning In your own words, define surface area. List 3 real life examples where you would need to find surface area.

4 Surface Area of Prisms Surface area of a polyhedron is the sum of the areas of its faces. The surface area of any prism is the sum of the areas of the bases and the lateral faces. S = areas of bases + areas of lateral faces

5 Surface Area of a Rectangular Prism SA = 2(lw + lh + wh)

6 Surface Area of Triangular Prisms SA = Area of three rectangles + Area of two triangles

7 Modeling Find the surface area of the prism.

8 Practice Find the surface areas of the rectangular prisms

9 Modeling Find the surface area of the prism.

10 Practice Find the surface areas of the triangular prisms

11 Practice Fifty percent of the surface area of the bread is crust. What is the height h?

12 Practice Which prism has the greater surface area?

13 Practice Draw and label a rectangular prism that has a surface area of 158 square yards.

14 Practice Find the surface area.
