A pyramid with 18 edges would be called a nonagonal pyramid. A prism with 18 edges is called a hexagonal prism.
There are 10 sides : 9 sides and the nonagonal base.
Edges: 27 Faces: 11 Vertices: 18
Base has 9 vertexes and then the point at the top makes 10.
16 edges- the edges of the base, and the edges leading to the point of the pyramid.

A nonagonal shape has 9 sides
There are many possibilities. A nonagonal pyramid A hexagonal prism A hexagonal dipyramid are three.
9
There are 10 sides : 9 sides and the nonagonal base.
9.....
A nonagonal prism has nine faces. It has a total of 18 vertices. A nonagonal prism also has 27 edges.
A nonagon has 9 sides
Edges: 27 Faces: 11 Vertices: 18
10. For any pyramid, it will be one more than the number of vertices in the base.
a pyramid has 8 edges
