Faces, Edges and VerticesFaces are flat surfaces on the shape. Edges are straight lines that define the sides of the polygons that make up each face of the shape. Vertices (or corners) are points where at least three edges meet. Some common examples are Cube 6 Faces 12 Edges 8 Vertices Rectangular Prism 6 Faces 12 Edges 8 Vertices Square Pyramid 5 Faces 8 Edges 5 Vertices Triangular Prism 5 Faces 9 Edges 6 Vertices Triangular Pyramid (Tetrahedron) 4 Faces 6 Edges 4 Vertices Pentagonal Prism 7 Faces 15 Edges 10 Vertices Pentagonal Pyramid 6 Faces 10 Edges 6 Vertices Hexagonal Prism 8 Faces 18 Edges 12 Vertices Hexagonal Pyramid 7 FORS 12 Edges 7 Vertices Octagonal Prism 10 Faces 24 Edges 16 Vertices
