This document describes the properties of several 3D geometric shapes including a hexahedron, tetrahedron, dodecahedron, sphere, and cone. It lists the number of edges, faces, and vertices for each shape, with the hexahedron having 6 edges, 12 faces, and 8 vertices, the tetrahedron having 4 faces, 6 edges, and 4 vertices, and the dodecahedron having 30 edges, 12 faces, and 20 vertices. The sphere and cone are also included and have 0 edges, 0 or 1 faces, and 0 vertices.
