The shape would be impossible. The faces and vertices have to add up to two more than the edges.
Three faces, two edges and 0 vertices.
Three faces, two edges and 0 vertices.
There are two plane faces and a curved face, two edges and no vertices.
Conventionally, two faces, one edge and one vertex.
Three dimensional objects have edges, vertices and faces. A face is a plane surface which forms a boundary of the shape. Two faces meet along a line which is an edge. Three or more faces meet at a point which is a vertex.
You cannot have such a shape because either the shapes must meet at an edge or the vertices must be joined by an edge.
Cylinder * * * * * There is no convex 3-dimensional shape with these qualities. A cylinder has two plane faces plus a curved one, and two edges.
One edge, no vertices and two faces.
Triangular prism
triangular prism
A cylinder has 0 vertices. If an edge is defined by the meeting of two faces then there are two edges but if an edge is defined by the meeting of two PLANE faces then there are 0 edges.
