Answer:

Explanation:

Volume of a cube is equal to its edge length (side) cubed.

If the volume is 216 - then the cube root of 216 = the side edge length.

Cube root of 216 = 6.

So the side length of each edge is 6.

The are of each face is equal to the side length squared.

6 times 6 = 36 units squared.

The area of each face is 36 units squared.
