In geometry, the octagonal prism is the sixth in an infinite set of prisms, formed by square sides and two regular octagon caps. If faces are all regular, it is a semiregular polyhedron.
- A prism composed of octagonal faces is called octagonal prism.
- The two faces at either end are octagons and the rest of the faces are rectangular.
Number of faces, edges and vertices
- Number of faces: 10.
8 vertical faces,
one at top
and one at the bottom
- Number of edges: 24
8 edges around the top face
8 vertical edges
8 edges around the bottom face
- Number of vertices:16
8 vertices where the top edges meet the vertical edges
8 vertices where the bottom edges meet the vertical edges
