The edge of a cube is 5 cm. Find the surface area of the cube.

A cube is a hexagon with all six sides being squares.

If a cube has six faces and they are squares, then the surface area of the cube will consist of the sums of the areas of six squares.

Recall that the area of a square is calculated by the formula:

S = a ^ 2;

S is the area of the square;

a – side of the square.

Find the area of one face of a cube (square):

S = 5 ^ 2 = 25 cm ^ 2.

Find the surface area of a cube by multiplying the area of the square by 6:

S pov. cube = 25 cm ^ 2 * 6 = 150 cm ^ 2.

Answer: 150 cm ^ 2.
