An octagonal pyramid has 16 edges.
16 edges
Octagonal pyramid: 9 faces 16 edges 9 vertices.
16 edges- the edges of the base, and the edges leading to the point of the pyramid.
An octagonal pyramid has 9 faces and 14 edges. The base of the pyramid is an octagon with 8 faces, and the pyramid itself has an additional triangular face. The edges consist of the edges of the octagon base and the edges connecting the base to the apex of the pyramid.
It is an octagonal pyramid and has 9 edges and 9 vertices.

An octagonal pyramid has 9 faces, 9 vertices, 16 edges.
16 edges, 9 vertices.
An octagonal pyramid has nine vertices. In addition, it has sixteen edges and nine faces, including an octagonal base and eight triangular faces.
There are many possible configurations for a decahedron and they have different numbers of edges: For example: A nonagon based pyramid: 18 edges An octagonal prism : 24 edges A pentagonal dipyramid: 15 edges.
