A cube has 6 faces, so the surface area of ONE face = 54/6 = 9
Each face of a cube is a square, so let's let x = the length of one side of that square
The area of a square = (side length)²
If the area of ONE face = 9, then we can write x² = 9, which means x = 3
So, each side of the cube has length 3
Volume of a cube = (side length)³ = (3)³ = 27
