| To solve this problem, remember that a cube is a hexagon in which all 6 faces are equal squares. The cube has 12 equal edges. Let’s calculate what the surface area of the cube is, knowing that its edge is 11 centimeters. The area of a square is equal to the square of its side. S = a ^ 2.

S = 6 * 11 * 11 = 6 * 121 = 726 sq. Cm.

Let’s calculate what is the sum of the edges of the cube.

11 * 12 = 132 cm.

Answer: 726 sq. Cm. 132 cm.
