Augmented Rhombicuboctahedron II (adapted from Leonardo)


This is a second interactive versión of Leonardo da Vinci's drawing of the augmented rhombicuboctahedron.
Leonardo da Vinci made several drawings of polyhedra for Luca Pacioli's book 'De divina proportione'. Here we can see an adaptation of the augmented rhombicuboctahedron.
In this version we can see the interior of this polyhedron. Luca Pacioli wrote that 'you can only see the interior using your imagination'. We can separate the pyramids and see that the interior is a rhombicuboctahedron. You can play with an augmented rhombicuboctahedron with different pyramids sizes clicking the next link: REFERENCES

This polyhedron is also called Elongated Square Gyrobicupola. It is similar to the Rhombicuboctahedron but it is less symmetric.
Adding six pyramids to a cube you can build new polyhedra with twenty four triangular faces. For specific pyramids you get a Rhombic Dodecahedron that has twelve rhombic faces.

You can build a Rhombic Dodecahedron adding six pyramids to a cube. This fact has several interesting consequences.
The first drawing of a plane net of a regular octahedron was published by Dürer in his book 'Underweysung der Messung' ('Four Books of Measurement'), published in 1525 .
Using cardboard you can build beautiful polyhedra cutting polygons and glue them toghether. This is a very simple and effective technique. You can download several templates. Then print, cut and glue: very easy!
Material for a session about polyhedra (Zaragoza, 7th November 2014). We study the octahedron and the tetrahedron and their volumes. The truncated octahedron helps us to this task. We build a cubic box with cardboard and an origami tetrahedron.
