An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The number of triangles will depend on which one of the 257 shapes you have in mind:All 8 faces of a quadrilateral based bipyramid will be triangles.A heptagon based pyramid has 7 triangular faces.A hexagonal prism has none.

How many triangular faces does a octahedron have?

An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. An octahedron can have triangles for all eight faces or, as is the case with a hexagonal prism, not a single triangular face.


What is the difference between a octahedron and a triangular prism?

One difference: An octahedron has 8 faces, a triangular prism has 5. An octahedron (="eight faces") is a regular high-symmetry solid with all the faces identical. A triangular prism has a triangular base, a triangular roof, and 3 rectangular sides (walls).
