1. Rectangular Prism Cylinder SPI 6.4.5 I CAN determine the surface area of a 3-D figure.

2. The surface area of a three- dimensional figure is the sum of the areas of its surfaces. A net is the pattern made when the surface of a three- dimensional figure is layed out flat showing each face of the figure.

3. top back end front end bottom = Imagine cutting a cardboard box along its edges and laying it out flat. The resulting figure is called a net.

4. Notice that all sides lay out to be triangles. =

5. 6 10 6 7 6 66 6 7

6. Surface Area of Square Pyramid Pyramids that have a square base have a total of five surfaces.

7. Square Pyramid S = area of square + 4  (area of triangular face) ‏ The surface area is 161 ft 2.

8. Square Pyramid 5.6 ft 4.8 ft

9. Triangular Prism 6 in 3 in

10. Surface Area of a Cylinder A cylinder has a total of three surfaces: a top, bottom, and middle. The top and bottom, which are circles, are easy to visualize. The area of a circle is πr 2 http://www.youtube.com/watch?v=Hgwii3Z0MxU

11. Surface Area of a Cylinder S = area of curved surface + 2  (area of each base) ‏ S = h  (2r) + 2  (r 2 ) ft
