There is no such shape - unless there are other faces. If there is one rectangular face then you require at least four other faces - one on each edge of the rectangle - making a minimum of 5 faces.

The following are some examples of a shape with two flat face and one curved surface: A sphere intersected by two planes. An ellipsoid intersected by two plane faces. A paraboloid intersected by two plane faces. A cone intersected by two plane faces. A cylinder. A hyperboloid intersected by two plane faces.
A shape that when you draw a line on the shape and cut along the line you get two identical shapes. A circle is an example.
A prism.
A prism.
Prism, which a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms.
This is the definition for the 3-D shape called a prism. There are different types of prisms, including a cube and a square prism.
it has six sides, 4 identical faces and two identical bases
It is a triangular prism.

A prism.
A triangular prism, where the two ends are triangles.
A right triangular prism has two identical faces. Two faces may or may not be identical in an oblique prism, in which the lateral edges are not perpendicular to the bases.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. All but one are not antiprisms: only the regular octahedron is.An antiprism is a solid shape comprising two identical parallel faces joined together with a "ring" of triangles alternately pointing in opposite directions. Consider a regular octahedron placed on one of its faces - a triangle. Its top face will be another identical triangle which points in the opposite direction. Between the top and bottom, there are six triangles, alternately pointing up and down. It therefore meets all the requirements of an antiprism.
A polygon. A prism has two identical bases or end-faces and these can be polygons with any number of sides.
Prism, which a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms.
