There are eight vertices on the surface of a cube, and each vertex has three right angles, so there are 24; Inside, the weight of each side is at most two faces, so there is 12 * 2 = 24.

A regular hexahedron has the following characteristics.

1, a regular hexahedron has eight vertices, and each vertex has three sides connected.

2. A regular hexahedron has 12 sides, and each side has the same length.

A regular hexahedron has six faces, and each face has the same area and shape.

Planar truncated cube

The following triangles, rectangles, squares, pentagons, equilateral pentagons, equilateral hexagons, diamonds and trapezoid can all be obtained by cutting a cube with a plane. The specific cutting method is as follows:

(1) triangle: a line passing through the diagonal between the vertex and the opposite side.

(2) Rectangle: Through two opposite sides or an edge.

(3) Square: parallel to a surface.

(4) Pentagon: passing through points on four sides and a vertex or points on five sides.

(5) Hexagon: passing through points on six sides.

(6) Regular hexagon: passing through the midpoint of six sides.

(7) Diamond: Through the opposite vertex.

(8) Trapezoid: passing through two parallel lines with different lengths on opposite faces.
