Reihe III, Nr 111

Cube with two inscribed tetrahedrons, which is half of the surface, contains an octahedron.


Mathematical description
The model represents the cube (in iron) and its inscribed octahedron (also in iron). One is the dual of the other. The dual of a Platonic solid can be computed by connecting the midpoints of the faces, and constructing the corresponding polygon. The model also illustrates two tetrahedra (in yellow string), whose intersection is the mentioned octahedron. The diagonals of the cube are represented in pink string.
