hexagonal prism
A triangular prism or a cuboid as it seems would fit the given description
Three congruent rectangles.
The lateral faces will be parallelograms, and the opposite faces will be congruent. In a right prism, the lateral faces will be rectangles.
A prism.
It is called a prism.

A prism.
In its most generalised form it comprises two connected, congruent and parallel faces: these faces are called the bases. In a right prism, the bases are at right angles to the length of the prism. In a polyhedral prism, all faces are polygons and, in such a case, the faces joining the bases are quadrilaterals. In the very special case of a right polyhedral prism, the bases are polygons and the lateral faces are rectangles.
The description given could fit that of a triangular prism.
