A rectangular prism is the only shape that is made up from only rectangular faces. But there are countless shapes which contain rectangular faces along with other shapes.
Rectangle
The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height of the prism. This formula calculates the total area of all six faces of the rectangular prism. It is derived from the formula for the surface area of a box, which consists of three pairs of identical rectangular faces.
A rectangular prism that is 4 cubes by 2 cubes is made up of 8 cubes.
Of rectangles and squares.

rectangular pyramid
The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height of the prism. This formula calculates the total area of all six faces of the rectangular prism. It is derived from the formula for the surface area of a box, which consists of three pairs of identical rectangular faces.
A rectangular prism has 6 flat surfaces
Triangular Prism
The shape is a triangular prism. This is a 3-dimensional polygon with two ends that are triangles and three rectangular sides connecting them.* * * * *FYI, a 3-dimensional polygon is known as a polyhedron.
A trianglular prism is made up of triangles and rectangles, so its net must have the same shapes.
A cube or a cuboid has 6 faces, 12 edges and 8 vertices.
