Calculate the surface area and the sum of the lengths of all edges of a cube whose edge is 5 cm.

To solve this problem, remember that a cube is a hexagon in which all faces are squares. There are 12 edges in a 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 its edge is 5 centimeters.

S = 6 * 5 * 5 = 6 * 25 = 150 square centimeters.

Let’s calculate the sum of the lengths of all edges of the cube.

12 * 5 = 60 centimeters.

Answer: 150 cm2, 60 cm.
