A prism has 2n vertices, where n is the number of sides in its base polygon. This is because each side of the base polygon is connected to another side by a vertical edge, and each vertex is formed at the intersection of two edges. So, a prism with a pentagonal base would have 10 vertices (5 vertices from the base polygon and 5 vertices from the top polygon).

A prism is a generic term used to describe a polyhedron with a pair of parallel and congruent polygonal base and a number of rectangular faces linking the two bases. A prism whose base is a polygon with n-sides (or vertices) has n+2 faces, 2n vertices and 3n edges, where n ≥ 3.
This depends on the type of prism. A prism has an even number of vertices, and at least 6 (a triangular 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.
14 vertices
A pentagram is a five pointed star and has 10 vertices. So, a pentagram prism has 20 vertices. This is NOT the same as a pentagonal prism.
A decagonal prism has 20 vertices: 10 at each end.
A hexagonal prism has 18 edges and 12 vertices.
