To solve this problem, remember that a cube is a hexagon in which each face is a square. Let’s calculate what is the surface area of the cube. The area of a square is equal to the square of its side. S = a ^ 2. Let’s calculate the surface area of a cube, knowing that the side is 11 centimeters.
S = 6 * 11 * 11 = 726 sq. Cm.
The cube has 12 equal edges. Let’s calculate the sum of the edge lengths.
12 * 11 = 132 centimeters.
Answer: 726 sq. Cm. 132 centimeters.
