## Presentation Transcript

1. Surface Area

2. Rectangular Prism The surface area S.A. of a rectangular prism with base l, width w, and height h is the sum of the areas of its faces. S.A. = 2lh + 2lw + 2hw

3. Practice Problem 1 Find the surface area of the rectangular prism shown to the right.

4. Triangular Prism To find the surface area of a triangular prism, it is more efficient to find the area of each face and calculate the sum of all of the faces.

5. Practice Problem 2 Find the surface area of the triangular prism shown to the right. Find the area of each shape and add. Area of rectangle 1 Area of rectangle 2 Area of rectangle 3 Area of the triangles

6. Surface Area of a Cylinder The surface area S.A. of a cylinder with height h and radius r is the area of the two bases plus the area of the curved surface (parallelogram). Model Net Area 2 circular bases 2 congruent circles with radius r 1 curved surface 1 rectangle with width h and length

7. Practice Problem Find the surface area of the cylinder. Round your answers to the nearest hundredth.
