SURFACE AREA Math 7
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
Rectangular Prism h w l Formula: Total Surface Area = 2wl + 2lh + 2wh Plug the numbers in and show work!
Find the Surface Area: 7m 3m 12m -Label each dimension first -Get the formula -Show work!
Cube s Formula: Total Surface Area = 6s2
Find the Surface Area: 8cm -The only dimension to label is s -Get the formula -Show work!
Cylinder r h Formula: Total Surface Area = 2∏rh + 2∏r2 Plug the numbers in and show work! Do not multiply by pi until the very end!
Find the Surface Area: 6in 9in -Label the dimensions -Get the formula
Find the Surface Area: 14in 10in -Label the dimensions -Get the formula
Triangular Prism refer to formula sheet for picture and formula Total Surface Area = wh + lw + lp + ls Just plug and chug!
