An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. One of these 257 shapes is a prismoid, and a prism is a special case of a prismoid in which the two hexagonal faces are congruent and parallel.

How many vertices does a octahedron prism have?
An octahedron shape is one which has 8 faces. Since it is a prism it must be a hexagonal prism (2 hexagons and 6 rectangles = 8 faces). And a hexagonal prism has 2*6 = 12 vertices.
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).
What is an eight sided 3-D shape called?
Many options. A pentagonal prism or a regular octahedron, for example.
Who invented the hexagonal prism?
In geometry, the hexagonal prism is a prism with hexagonal base. This polyhedron has 8 faces, 18 edges, and 12 vertices.[1] Since it has 8 faces, it is an octahedron. However, the term octahedron is primarily used to refer to the regular octahedron, which has eight triangular faces. Because of the ambiguity of the term octahedron and tilarity of the various eight-sided figures, the term is rarely used without clarification.

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.
