Cubes are special quadrangles, cuboids, triangles, rhombic polyhedrons and parallelograms, just as squares are special rectangles, rhomboids and parallelograms.

The formula of the side length of a cube is as follows: if the volume of the cube is V and the side length is A, then the cube with A is equal to V, and the formula of the side length is that A is equal to the cube root number of V; If the surface area of a cube is s and the side length is a, the square of a is equal to s divided by 6.

The formula of side length is that a is equal to 6s of root sign; If the total side length of the cube is c and the side length is a, then a is equal to c divided by12; If the area of a face of a cube is s and the side length is a, the square of a is equal to s, and the formula of the side length is that a is equal to the root sign s.

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 known as a cube and a regular hexahedron. Cubes are special cuboids.

The benefits of learning mathematics:

1. Mathematics can cultivate people's integrity and honesty. Mathematics pays the most attention to convincing people by reasoning, and only believes in the results of logical reasoning.

Mathematics can cultivate people's tenacity and courage. Paulia, a great math educator, thinks that difficulties and problems belong to the same concept. If there is no difficulty, there will be no problem.

3. Mathematics can cultivate people's overall consciousness. To solve mathematical problems, we must comprehensively consider the problems from the known to the conclusion and grasp the interrelationships of all aspects. Mathematics teaching can cultivate students to consider problems comprehensively from the overall situation.

Mathematics can cultivate people's good character. The better a person's math study, the more flexible his thinking. In this case, his enthusiasm and enthusiasm are very high, and he is good at expressing his ideas and methods, so that his communication skills will be tempered and his self-confidence will be gradually enhanced.
