How many faces does a rhombicuboctahedron have?
26 faces
The Great Rhombicuboctahedron has 12 square faces, 8 regular hexagonal faces, and 6 regular octagonal faces for a total of 26 faces. This solid also has a total of 48 vertices and 72 edges.
Who invented rhombicuboctahedron?
In 340 AD, Pappus of Alexandria attributed the discovery of the rhombicuboctahedron to Archimedes, in 200 BC. The theory is that Archimedes described twelve other semi-regular polyhedrons in a work that did not survive.
What is a rhombicuboctahedron used for?
The rhombicuboctahedron is used in three uniform space-filling tessellations: the cantellated cubic honeycomb, the runcitruncated cubic honeycomb, and the runcinated alternated cubic honeycomb.

What is a rhombicuboctahedron?
In geometry, the rhombicuboctahedron, or small rhombicuboctahedron, is an Archimedean solid with eight triangular and eighteen square faces.
What are the special orthogonal projections of a rhombicuboctahedron?
The rhombicuboctahedron has six special orthogonal projections, centered, on a vertex, on two types of edges, and three types of faces: triangles, and two squares. The last two correspond to the B 2 and A 2 Coxeter planes.
