Polyhedron Model by Martin Berman, Gyroelongated Pentagonal Cupola

National Museum of American History

Object Details

Berman, Martin
Description
The bottom of this model is a regular decagon, the top a regular pentagon. Above the decagon are twenty triangular faces. Above these are five squares which alternate with five triangles. Hence the faces are twenty-five equilateral triangles, five squares, one regular pentagon, and one regular decagonal.
On Berman's models of regular-faced convex polyhedra, see 1978.1065.01.
