A prism has edges that are formed by the intersection of its faces. Specifically, a prism features three types of edges: the lateral edges, which connect the corresponding vertices of the two parallel bases; and the base edges, which are the edges of the two bases themselves. The total number of edges in a prism is equal to the number of edges in one base multiplied by two, plus the number of lateral edges. For example, a triangular prism has 9 edges: 3 from each triangular base and 3 lateral edges connecting the bases.
A triangular prism has 6 edges and so an octagonal prism will have 16 edges.
