Materials: cardboard, crayons, scissors, glue.

The manufacturing method is as follows:

1. First, prepare a piece of cardboard;

2. Draw six square faces on the cardboard;

3. Color the six squares, and then fold the cardboard into creases along the edges of the squares;

4. Then use scissors to cut along the outline of the square and the pasted part;

5. After cutting, use glue to paste the pasted part from one square, and paste all six squares, and it is ready.

A three-dimensional figure surrounded by six identical squares is called a cube. A straight parallelepiped with square sides and bottom is called a cube, that is, a hexahedron with equal sides, also called a cube or a regular hexahedron. Cubes are special cuboids. There are 6 faces, 8 vertices and 12 edges.

Cube:

A cube is a special polyhedron with six faces, twelve sides and eight vertices. Every face is an equilateral square. The diagonal length of the cube is equal to 3 times the square root of the side length.

The volume of a cube can be calculated by the cube with side length, that is, V=a? Where a is the side length of the cube. The surface area can be calculated by multiplying the square of the side length by 6, that is, S=6a? .

Cubes have many special properties and applications. For example, it can be used to represent symmetry and geometric relations in three-dimensional space. In architecture and design, cubes can be used to build stable structures, such as the foundation of houses or the support of bridges. In addition, cubes can also be used for models and experiments in mathematics and physics.

In a word, cube is a simple and important geometric shape, which has extensive application and research value in various fields.
