A cube is a type of hexahedron which is three-dimensional, having six square faces, shaped like a box. These six squares are regular square prisms arranged in three orientations, and so is also called a square parallelepiped. A cube which is the only regular hexahedron may be solid or hollow, and is one of the five Platonic solids. Volume of cube is calculated by multiplying the length of one edge thrice by itself.
