The face of a cube is a square. In a square, all sides are equal, which means that the length of its side (which, in turn, is the edge of the cube) is 12/4 = 3 cm.
Then the area of one face of the cube is 3 * 3 = 9 cm ^ 2.
The cube has only 6 faces, which means that the area of its entire surface is 6 * 9 = 54 cm ^ 2.
