I assume that we're talking about an ordinary polyhedron that looks topologically like a sphere, not like some kind of torus or multi-sheeted sphere or whatnot. Apply Euler's Formula: VerticesâEdges+Faces = 2, for a polyhedron. Plugging in your numbers gives Vâ24+10 = 2, from which we see that V = 16. Alternative solution: Draw an octagonal prism, and confirm that your figure has 16 vertices, 10 faces, and 24 edges. Written Apr 13, 2013 Â· View Upvotes.
Vertices, Edges and Faces. A vertex is a corner. An edge is a line segment that joins two vertices. A face is an individual surface. Let us look more closely at each of those: A vertex (plural: vertices) is a point where two or more lines meet. It is a Corner. This tetrahedron has 4 vertices.
