WebThe polyhedron has 8 triangular faces and 6 octagonal faces. Since each edge of the polyhedron is shared by two faces, its total number of edges is (8×3+6 ×8)/2=36. 1 Each octagonal face has 20 diagonals. So the number of diagonals of the polyhedron on its faces is 6×20 = 120. 1 The number of pairs of vertices of the polyhedron is ˜ 24 2 ...
