no not all pyramids are polyhedron because each pyramid has a different shape. so no each pyramid is not a polyhedron

Yes they are.
No. Polyhedrons are any shape with multiple sides. A triangle and a prism are just two different kinds of polyhedrons.
they are not sometimes prisms
Not true.
not all
These could be called solids.There are lots of three dimensional shapes. Cubes, spheres, cylinders, cones, toroids, pyramids, helixes, the various polyhedrons..

Polyhedrons such as pyramids and cuboids
Yes, pyramids are considered polyhedrons because they are three-dimensional geometric shapes with flat polygonal faces. A pyramid has a polygonal base and triangular faces that converge at a single point called the apex. The number of triangular faces corresponds to the number of sides on the base polygon, making pyramids a specific type of polyhedron.
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.
not all, but some

tetrahedrons
All polyhedrons.
