How to find the area of ​​a cube

How to find the area of ​​a cube

Cube called regular polyhedron, each face of which is a square.

Cube area is called the area of ​​its surface, which is the sum of the areas of its faces, that is, the sum of the squares of the squares, which form a cube.

You will need

  • Basic knowledge of solid geometry.

instructions

1

We calculate the area of ​​one face of the cube. As 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 edges of the cube in the box. For example, the cube edge length is equal to 5, then the area of ​​its faces 5 * 5 = 25.

2

The area of ​​the surface of the cube consists of six equalinterconnected facets. Consequently, the entire surface area of ​​a cube is equal to the area of ​​one face six times taken. Multiply the area of ​​the face and get a six-surface area of ​​the cube. For example, the area of ​​the face is 25, then the surface area of ​​the cube 25 * 6 = 150.
