A regular polyhedron is called a cube, each face of which is a square.
The area of the cube is called the area of its surface, which consists of the sum of the areas of its faces, that is, the sum of squares that form a cube.

Let us calculate the area of one face of the cube. Since the face of the cube is a square, the area of the face is equal to the area of the square, that is, the length of the edge of the cube in the square. For example: the length of the edge of the cube is equal to 5, then the area of its edge is 5 * 5 = 25.
The surface area of the cube consists of six equalBetween each other. Consequently, the surface area of the whole cube is equal to the area of one face taken six times. Multiply the face area by six and get the surface area of the cube. For example, the area of the face is 25, then the surface area of the cube is 25 * 6 = 150.
