This polyhedron has seven faces, 14 vertexes, 21 edges, and a hole. Topologically, if it were smoothed out, it would be equivalent to a doughnut (or torus). You could describe as a toroidal ...

Several thousand infectious particles are incorporated in an average polyhedron with edges 2 micrometres long, occupying about 10–15% of the total volume of the crystal. Therefore, the ...

A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles ...
