14 vertices
i have no clue * * * * * An octahedron is the name for a non-specific shape. It could, as described above, be a di-rectangular pyramid with 6 vertices. Or it could be a heptagonal pyramid, in which case it has 8 vertices. Or it could be a hexagonal prism, in which case it has 12 vertices. There are other octahedraons.
There are 2606 distinct convex nonahedrons with varying numbers of vertices, such as Johnson solid #14 (a triangular prism sandwiched between two pyramids) which has 8, and the heptagonal prism with 14. Concave solids could have even more!
There can be a heptagonal prism or an octagonal prism, but there is no such thing as a hectagonal prism.

A pentagonal prism has 10 vertices. A rectangular prism has 8 vertices. Therefore, a pentagonal prism has 2 more vertices than a rectangular prism.
It has 14 vertices
A prism with 9 faces is a heptagonal prism. That has 14 vertices.
A heptagonal what? Prism, pyramid or something else?
14. And it is better known as a heptagonal prism.
l
Faces: 9 Vertices: 14 Edges: 21
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
Heptagonal prism
A heptagon is a 7-sided polygon, so a heptagonal prism is a 3D version of that (9 sides, 21 edges, 14 vertices).
A heptagonal prism gas 21 edges.
A heptagonal prism has 14 vertecies and 21 edges.
