If the total surface area of a cube is 302.46ft2 what best describes the length of the side of the cube?

7.1ft

Step-by-step explanation:

The formula for calculating the total surface area of a cube is 2 (L²+L²+L²)

=2 (3L²)

= 6L²

Where L is the length of the cube

If the total surface area of a cube is 302.46ft², then

302.46 = 6L²

L² = 302.46/6

L² = 50.41

L = √50.41

L = 7.1ft

The length of the side of the cube is 7.1ft
