Each face of a cube is represented by a square, the perimeter of which is determined by the formula:
P = 4a. Provided that this value for one such face is 12 cm, we find the length of the edge (corresponds to the partial product and the first factor):
a = P: 4 = 12: 4 = 3 cm.
The surface area of a cube is calculated using the formula:
S = 6a² = 6 * 3 * 3 = 54 cm².
