They have compound names which use Greek prefices for the number of faces, and the suffix "hedron".
So, an octahedron would be a solid with 8 faces.
A Rectangle
Dodecahedron.
Rectangular Prism
That one.
A cube
Dodecahedron.
A Rectangle

Rectangular Prism
Any sort of prism.
Well, darling, those solid figures with more than six faces are called polyhedrons. They're like the cool kids of geometry, strutting around with their multiple faces and edges. So next time you see one, just remember they're not just any old shape - they're polyhedrons, honey.
A cube
A polyhedron is a solid figure with many plane faces, typically more than six.
Since a cube has 6 faces, you would be looking for a solid shape with only 2 faces and no such solid exists.
Any polyhedron a prefix that stands for a number greater than 6.
A solid figure that has some of the same faces but some different faces, and has one more face than the other, is a prism and a pyramid. A prism has two identical bases and rectangular or square faces, while a pyramid has a polygonal base and triangular faces that meet at a single point, called the apex. The prism has one more face than the pyramid.
A tetrahedron has four faces and six edges.
