Use the formula SA=6s2 , where SA is the surface area and s is the edge length of the cube, to solve this problem. Gavan must paint a cube-shaped box. The edge length of the box is 212 feet. What is the surface area of the box?

*A cube has 6 surfaces. Every surface has the same area.

--------------------------------------------------------------------------------------
Find one face
--------------------------------------------------------------------------------------
Area = Length x Width
Area = 212 x 212
Area = 44,944 ft²

--------------------------------------------------------------------------------------
Find 6 faces
--------------------------------------------------------------------------------------
1 face = 44,944 ft²
6 faces = 44,944 x 6
6 faces = 269,664 ft²

--------------------------------------------------------------------------------------
Answer: Total Surface area = 269,664 ft²
--------------------------------------------------------------------------------------

First you plug in 212 as s.

6(212) 2

The order of operations says you have to do exponents first.
(212)2= 44944

Then your equation is
6(44944)=269644 square feet
