To solve this problem, remember that a cube is a hexagon with all 6 faces – squares. The surface area of a square is equal to the product of the area of one face by their number, that is, by 6. Let the side of the cube be a.
S = a * a * 6.
Knowing that the surface area of the cube is 96 sq. Cm, we calculate what the edge of the cube is equal to.
a ^ 2 * 6 = 96;
a ^ 2 = 96/6;
a ^ 2 = 16;
a = 4;
Answer: 4 centimeters.
