Yes.
An octagonal-based prism has 8 perpendicular faces, which are the vertical rectangular faces connecting the edges of the octagonal bases. Additionally, it has 2 octagonal faces on the top and bottom, making a total of 10 faces overall. However, only the 8 rectangular faces are perpendicular to the octagonal bases.
An octagonal prism has: 10 faces 16 vertices and 24 edges :)
Octagonal prism.
No.
An octagonal prism has 10 faces, 24 edges and 24 edges(!) Oh, and in case you are interested, 16 vertices.
An octagonal prism has: 10 faces 16 vertices and 24 edges :)
Prisms with any number of sides can have perpendicular faces. Often both end faces are perpendicular to the length. In the case of a REGULAR octagonal prism, there will be four pairs of parallel faces, where each face of a pair will be perpendicular to the two faces of one of the other pairs. There is not much that can be said with certainty about an irregular octagonal prism.
An octagonal prism has a base with eight edges.
A triangular prism has 6 edges and so an octagonal prism will have 16 edges.
