Twice the name. A prism with an n-sided base will have 2n vertices.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
A triangular prism has 5 faces, 9 edges and 6 vertices
the shape that has 8 faces , 18 edges , and 12 vertices is simply a hexagonal prism not a pyramid my butt :P
a prism always have 6 or 8 edges and vertices learn math dang * * * * * Good point! Learn math - or maths even. A prism is a generic name for a 3-d shape with two congruent polygonal "bases" with n-sides each, and n rectangles joining them together. That means a prism with a n-polygon base has 3n edges and 2n vertices.

A prism is often named according to its base: one of the pair of congruent and parallel polygonal faces. In that case, if the base is a polygon with n sides, then the prism has 2*n vertices.

An hexagonal prism would fit the given description

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.
Subtract 1 from the number of vertices. Find the name of the polygon with that many sides. The pyramid has that polygon as its base. So, for example, 7 vertices. Subtract one and that gives 6. A six sided polygon is a hexagon. So the shape is a hexagon based (or hexagonal) pyramid.
A triangular prism would fit the given description.
