### math is great by Brandon McGrew,Carla Lopez,Byron Couteeee

## Formula

*SA=6×**a**2*## Examples #1

**Example: Surface area of a cube with a side of length 4 = 4*4*6 = 96**## Examples #2

Find the surface area if the length of one side is 3 cm

Surface area = 6 × a2

Surface area = 6 × 32

Surface area = 6 × 3 × 3

Surface area = 54 cm2

## Examples #3

*SA=6×**a**2*

*SA = 6 × (8)**2*

*SA = 6 × (64)*

*SA = 384 cm**2** *
