WebA concave polyhedron has at least one face that is a concave polygon. A polyhedron that is not concave, is convex. Polyhedra can also be classified based on the number of faces it … WebSolution 2. We first find the number of vertices on the polyhedron: There are 4 corners per square, 6 corners per hexagon, and 8 corners per octagon. Each vertex is where 3 corners coincide, so we count the corners and divide by 3. . We know that all vertices look the same (from the problem statement), so we should find the number of line ...
