Truncated cuboctahedron (Great rhombicuboctahedron)

Truncated cuboctahedron

The polyhedron is obtained on the basis of the operation of mathematical expansion (for more detail, No. 21 of the Magic Edges).

A truncated cuboctahedron is a semiregular polyhedron with two properties:
1. All faces are regular polygons of three types - an octagon, a hexagon and a quadrilateral;
2. For any pair of vertices, there is a symmetry of the polyhedron (that is, a motion that translates the polyhedron into itself) that transforms one vertex to another.


Truncated cuboctahedron is one of the 13 solids of Archimedes.

Archimedean solids are semiregular polyhedra in the sense that their faces are regular polygons, but they are not the same, while the condition of one of the types of spatial symmetry: tetrahedral, octahedral or icosahedral is preserved.

To assemble a truncated cuboctahedron, you will need to print two nets on A4 sheets.

For printing, you can use both white and colored paper.

If you are using a color printer, then we suggest downloading a color net of a truncated cuboctahedron.

We connect two parts of the net into a single net as shown in the figure:


Next, we glue the unfolding and get a polyhedron of a truncated cuboctahedron.

Video from our partners - the team "ART KOSEKOMA", clearly demonstrates how the net is converted into a geometric shape:

Truncated cuboctahedron from the set "Magic Edges"

semiregular polyhedra 21 400 2
For the assembly of a polyhedron, we can offer you ready-made nets - cut and folded.
To do this, you need to use the details of the set Magic Edges 21.
In addition, in the release itself you will find information about the structure of the polyhedron.
