Answer:

A cube is a three-dimensional shape with all its faces square and all its edges equal in length. 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).
