A nonagonal prism.
9 edges
A triangular prism has 3 sides on each base (2) and 3 on the lengths of the prism therefore it has 9 edges.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. 18 base edges and 9 lateral edges
In all 9 edges are present. (3 edges at the triangular base of prism and 3 edges on the opposite triangular face. And, 3 edges connect the two faces of prism.)
An octagonal prism has a base with eight edges.
A prism with an n-sided base will have 2nvertices, n + 2 faces, and 3n edges.9 edges, 5 faces.
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.
9 edges, 6 vertices. A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
5 faces, 6 vertices, and 9 edges.
9 EDGES: triangular prism did you mean faces? Or vertices?
