There is no shape which has only three rectangle. And, if it has other faces, then there are many possibilities.
cuboid
It is a triagular prism

There is no 3D shape with 6 faces: 4 rectangles and 2 triangles. See the link for all forms of hexahedra.
Rectangles are two dimensional objects- they have no thickness. Therefore you cannot "stack" them and so there will be no 3-D shape.
A box is a 3D shape with 6 rectangles (a box could also include squares). The rectangles are: Top/Bottom/Front/Back/Side/Side
It is a triangular prism that fits the given description.
