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.

You will need

• Basic knowledge of stereometry.

Instructions

1

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.

2

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.
