An octahedron has8 faces, 12 to 18 edges and 6 to 12 edges.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. An octahedron can have 6 to 12 vertices, and 12 to 18 edges.
Three edges meet at each vertex.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The number of edges meeting at a vertex can vary between 3 and 7 - depending on the specific octahedron.
