I believe it is a cone, a cylinder has three faces.
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.
Cylinder * * * * * There is no convex 3-dimensional shape with these qualities. A cylinder has two plane faces plus a curved one, and two 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.
the place where two faces intersect
Conventionally, two faces, one edge and one vertex.
It is a 1-dimensional place where two faces come together.
A cylinder would fit the given description.
Triangular prism
Square pyramid.
Well, isn't that just delightful! It sounds like A is a special kind of shape called a polyhedron. You see, in a polyhedron, each edge connects two faces together. So if A has twice as many edges as faces, it must be a very harmonious shape with a lovely balance between its edges and faces.
