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!
Cube
There is no 3D shape with 6 faces: 4 rectangles and 2 triangles. See the link for all forms of hexahedra.
The 3D house shape is called a rectangular prism. It is a three-dimensional geometric solid that has six faces, all of which are rectangles. The rectangular prism is characterized by having three pairs of congruent and parallel faces, making it a type of parallelepiped.
it is called a triangular prism
A box is a 3D shape with 6 rectangles (a box could also include squares). The rectangles are: Top/Bottom/Front/Back/Side/Side
