In a cube, every face shares its edges with 4 other squares. In a net of a cube, not all edges of the squares are joined with another edge. Technically, a polyhedron is the boundary between the interior and exterior of a solid. In general, polyhedrons are named according to number of faces. A tetrahedron has four faces, a pentahedron five, and so on; a cube is a six-sided regular polyhedron (hexahedron) whose faces areSuch a polyhedron would either have to be assembled the same way as a cube consisting of kite (quadrilateral where each edge has an adjacent edge of the same length) surfaces or assembled like a triangular bipyramid. The proof is by considering a corner and then rule out the possibility that other than three faces meet there.
