Cube

A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex.

The cube can also be called a regular hexahedron and is one of the five Platonic solids.

It is a special kind of square prism, of rectangular parallelepiped and of 3-sided trapezohedron.

The cube is dual to the octahedron.

It has cubical symmetry (also called octahedral symmetry).

A cube is the three-dimensional case of the more general concept of a hypercube, which exists in any dimension.
