1. Preparation materials: scissors, glue, paper, ruler, pencil, etc.

2. Draw a square: Draw a square on the paper with a ruler and pencil and cut it out. This square will serve as the bottom of the cube.

3. Making a cube frame: Cut out some long strips of paper with scissors, and then glue them into a square frame. This frame should be as big as the square at the bottom.

4. Paste the bottom: paste the bottom square to the bottom of the frame.

5. Make other faces: Repeat steps 2 and 4 to make the other five faces and paste them on the frame.

6. Trimming: Trim the edge of the cube with scissors to ensure that it is flat.

7. Check the integrity: check whether the cube is complete. If there is a problem, it can be repaired with glue.

8. Finish making: Now you have a complete cube, which can be used for various purposes, such as teaching tools and decorations.

Cube application:

1, Architecture and Design: Cube is a basic geometric shape, which is often used in architecture and design. For example, cubes can be used to build buildings, design furniture, packaging boxes and so on.

2. Mathematics and Science: Cube is also an important concept in the field of mathematics and science. For example, in geometry, a cube is a geometric body with six faces, twelve sides and eight vertices. In physics, cubes can be used to simulate the states and properties of matter.

3. Computer graphics: In computer graphics, a cube is a basic three-dimensional shape, which can be used to construct more complex shapes and scenes. For example, game developers can use cubes to build buildings and scenes in the game.

4. Cryptography: In cryptography, cubes can be used to create encryption and decryption algorithms. For example, Caesar password is an algorithm that uses cubes for encryption and decryption.

5. Crafts: Cubes are also a common art form, which can be used to make sculptures, puzzles, mosaics and other artworks. At the same time, cubes can also be used to make handicrafts, such as making boxes and toys.
