1, summary of the characteristics of the cuboid of the math book. Math book cuboid is classical geometry.

2. Shape: The cuboid of a math book is a rectangle with six faces, each of which is a rectangle and parallel to each other.

3. Size: The size of a math book cuboid can be described by its length, width and height. The length of a cuboid refers to the dimension parallel to the long side, the width refers to the dimension parallel to the short side, and the height refers to the dimension perpendicular to the bottom.

4. Number of faces: A math book cuboid has six faces, each of which is a rectangle. These surfaces can be named in different ways, such as bottom surface, top surface, side surface and so on.

5, the number of vertices: the math book box has eight vertices, each vertex is the intersection of two faces. These vertices can be named in different ways, such as bottom vertex, vertex, side vertex and so on.

6. Number of sides: A math book cuboid has twelve sides, and each side is the dividing line between two faces. These edges can be named in different ways, such as bottom edge, top edge, side edge and so on.

7. Classification: Math book cuboids can be classified according to their characteristics. According to the ratio of length, width and height of cuboids, they can be divided into flat cuboids and cubes. The bottom surface of a flat cuboid is square or rectangular, and the side surface of the cuboid is square or rectangular.

Characteristics of rectangle

A rectangle is a parallelogram with four corners, two equal diagonals and equal bisectors. Two diagonal lines are equally divided, two opposite sides are parallel and two opposite sides are equal. All four corners are right angles.

That is, the square of the diagonal length of a 90-degree rectangle is the sum of the squares of both sides. A math book cuboid is a geometric body with six faces, eight vertices and twelve sides. Its size and shape can be described by length, width and height. In mathematics and practical applications, cuboids have a wide range of application values.
