Nonahedron
Nonahedron.
An octagonal pyramid.
Since it has 9 faces it is a nonahedron. Not sure how many of the thousands of nonahedrons have 6 vertices.
Triangular prism
Oh, what a happy little question! The shape you're describing is a nonagon, also known as a enneagon. It has 9 faces, 21 edges, and 14 vertices. Isn't it just fascinating how shapes come together in the art of geometry? Keep exploring and painting those beautiful shapes, my friend.
A triangular prism
It is a nonahedron.
A nonahedron, which is a 3D shape with 9 faces.
It is a triangular prism that has 6 vertices, 9 edges and 5 faces.
nonahedron
There is no simply connected 3-d shape because it is not consistent with the Euler characteristic.
