Icosahedron model
Sold
In geometry icosahedron (cherry wood) is a polyhedron with 20 triangular faces, 30 edges and 12 vertices. A regular icosahedron with identical equilateral faces is often meant because of its geometrical significance as one of the five platonic solids. Icosahedrite is a mineral (found in remote parts of russia) that has the crystal shape of an icosahedron. This model comes from the exhibition which is related to the five hundredth birthday of Luca Pacioli in 2009. 41 cm
