It is a triangular prism that fits the given description.
There is no 3D shape with 6 faces: 4 rectangles and 2 triangles. See the link for all forms of hexahedra.
You are describing a triangular prism. It has a rectangular base, two rectangular sides and two triangular ends.
A 3-d shape with 6 equal faces is a cube. It has 6 squares as it's faces. A 3-d shape with 6 equal faces and only 2 squares is a rectangular prism. It has 2 squares and 4 other rectangles (squares are rectangles too) as it's faces.
it is called a triangular prism
8 * * * * * There is no 3-D shape made from regular hexagons. The previous answer may refer to a hexagonal prism. But that is not a 3-D hexagon: the shape has two hexagonal faces and six rectangles - not just hexagons.
Oh, what a delightful question! If you stack rectangles on top of each other, you'll create a wonderful 3D shape called a rectangular prism. Just imagine those rectangles piling up so neatly and forming a solid shape with six faces, where each face is a rectangle. Keep on creating, my friend!

It is a triagular prism
There can be no closed 3D shape with only one square and 3 triangles.

No 3D shape with FLAT SIDES has exactly 3 faces. 4 is the minimum.
