The simplest answer is a cylinder (although you could squish it a bit to make something slightly different). It has a curved rectangular face, two circular faces, and two curved edges.
a cylinder
The shape would be impossible. The faces and vertices have to add up to two more than the edges.
A tetrahedral prism is a three-dimensional geometric shape that has two congruent triangular bases and four congruent lateral faces that are in the shape of triangles. The lateral faces connect the corresponding vertices of the two triangular bases, forming a solid with six faces, eight edges, and four vertices.
Cylinder * * * * * There is no convex 3-dimensional shape with these qualities. A cylinder has two plane faces plus a curved one, and two edges.
the place where two faces intersect
Conventionally, two faces, one edge and one vertex.
A cylinder would fit the given description.
It is a 1-dimensional place where two faces come together.
Square pyramid.
Triangular prism
A triangular prism ! It has a triangular face at each end, a rectangular base and two adjoining rectangular faces. It actually has nine edges and six corners.
