Cube
A regular polyhedron bounded by six congruent square faces, with 12 edges and 8 vertices. It is one of the five Platonic solids.
Given two cubes of the same size, you can drill a hole through one and pass the other through it. By drilling parallel to the space diagonal, a cube about 6% larger than the original can pass through. This is known as the 'Rupert property.'
