Polyhedrons such as pyramids and cuboids
polyhedrons need flat face and edges, corners which cylinder cones don't have.
Polyhedrons.
Polyhedrons are shapes with many faces
Not true.
they are not sometimes prisms
No. Polyhedrons are any shape with multiple sides. A triangle and a prism are just two different kinds of polyhedrons.

Polyhedrons such as pyramids and cuboids
no not all pyramids are polyhedron because each pyramid has a different shape. so no each pyramid is not a polyhedron * * * * * Yes they are.
Both pyramids and prisms are three dimensional. Both of them have polygon faces. Another thing common about pyramids and prisms is that they have a base and faces.
A prism is a polyhedron.
These could be called solids.There are lots of three dimensional shapes. Cubes, spheres, cylinders, cones, toroids, pyramids, helixes, the various polyhedrons..
Triangular prisms and square-based pyramids have 5 faces. Trapezoid prisms and cubes have 6 faces. Hexagonal prisms and octahedrons have 8 faces.
Yes, an empty box is and No, polyhedrons don't have to be.
