The truncated octahedron is a spacefilling polyhedron. The truncated octahedron is an Archimedean polyhedron and you can think it as a octahedron from which you have removed six half octahedra.
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.
Here we can see another point of view: A truncated octahedron is built by eight half cubes. This relation between the cube and the truncated octahedron can help us to understand the spacefilling property of this beautiful polyhedron.
We have already calculated the volume of half a cube. Then, the volume of a truncated octahedron is eight times the volume of half a cube:
Con ocho de estos medios cubos podemos construir un poliedro que tiene interesantes propiedades.
La primera de las propiedades de este poliedro es que como ya hemos calculado el volumen de medio cubo. Entonces el volumen de este poliedro es muy sencillo: You can play with the transparency in this mathlet version

Leonardo da Vinci made several drawings of polyhedra for Luca Pacioli's book 'De divina proportione'. Here we can see an adaptation of the 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 first drawing of a plane net of a regular tetrahedron was published by Dürer in his book 'Underweysung der Messung' ('Four Books of Measurement'), published in 1525 .

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.
