Dodecahedron

grabcad

A dodecahedron is a polyhedron with twelve regular pentagonal faces, making it one of the five Platonic solids. It has 20 vertices and 30 edges, with each face having the same size and shape. The word "dodecahedron" comes from the Greek words "dodeka," meaning twelve, and "hedra," meaning base or seat. This geometric shape is often used in art, architecture, and science due to its symmetrical properties.
