The Truncated Octahedron is a space filling polyhedron
The truncated octahedron is an Archimedean solid. It has 8 regular hexagonal faces and 6 square faces. ![]()
The truncated octahedron is an Archimedean solid. It has 8 regular hexagonal faces and 6 square faces. Its volume can be calculated knowing the volume of an octahedron.
It is a space-filling polyhedron. These polyhedra pack together to fill space, forming a 3 dimensional space tessellation or tilling. ![]()
Using eight half cubes we can make a truncated octahedron. The cube tesselate the space an so do the truncated octahedron. We can calculate the volume of a truncated octahedron.
Steinhaus, in his book 'Mathematical Snapshots' wrote:[The truncated octahedron] "fills the whole space in such a way that only 4 solids meet in each vertex; it is semiregular -which means that its faces are regular polygons. There is no other solid having these properties and thus it gives the simplest decomposition of space in congruent parts." (pag. 188) ![]() ![]() ![]() ![]()

We can cut in half a cube by a plane and get a section that is a regular hexagon. Using eight of this pieces we can made a truncated octahedron.

The volume of an octahedron is four times the volume of a tetrahedron. It is easy to calculate and then we can get the volume of a tetrahedron.

The stellated octahedron was drawn by Leonardo for Luca Pacioli's book 'De Divina Proportione'. A hundred years later, Kepler named it stella octangula.

The compound polyhedron of a cube and an octahedron is an stellated cuboctahedron.It is the same to say that the cuboctahedron is the solid common to the cube and the octahedron in this polyhedron.

When you truncate a cube you get a truncated cube and a cuboctahedron. If you truncate an octahedron you get a truncated octahedron and a cuboctahedron.
