The surface area of a cube is 216in.² what is the volume of a cube

Answer:216 in^3

Step-by-step explanation:

Length=L

Surface area=216

surface area=6 x L^2

216=6xL^2

Divide both sides by 6

216/6 = (6xL^2) / 6

36=L^2

L^2=36

Take the square root of both sides

√ (L^2) = √ (36)

L=6

Volume of cube=L x L x L

volume of cube=6 x 6 x 6

Volume of cube=216
