1 SURFACE AREA Math 7

2 The Surface Area of a given solid figure (3-Dimensional shape) is found by adding the areas of each surface of the figure together. There are formulas that can help us with this process. Since we are talking AREA, our units are square units

3 Rectangular Prism h w l Formula: Total Surface Area = 2wl + 2lh + 2wh Plug the numbers in and show work!

4 Find the Surface Area: 7m 3m 12m -Label each dimension first -Get the formula -Show work!

5 Cube s Formula: Total Surface Area = 6s 2

6 Find the Surface Area: 8cm -The only dimension to label is s -Get the formula -Show work!

7 Cylinder r h Formula: Total Surface Area = 2∏rh + 2∏r 2 Plug the numbers in and show work!

8 Find the Surface Area:
