Geometric Model, Semi-Regular Prism

Object Details

Benson, Harold Walter

This wooden model has three pentagonal faces, all of equal size, and five equilateral triangular faces, all of equal size. Two of the triangles are in parallel planes. Three other triangles surround one of these triangles. Three pentagons surround the other triangle.

Some hobbyists enjoy figuring out how to make attractive models of geometric surfaces. Harold Walter Benson, a machinist from Chicago, made this model in the 1990s, when he was retired and living in South Carolina.
