they are not sometimes prisms
Not true.
No. Polyhedrons are any shape with multiple sides. A triangle and a prism are just two different kinds of polyhedrons.
True. Some polyhedrons do not fit the definitions of prisms or pyramids. For example, a truncated tetrahedron is a polyhedron that has faces that are not all parallel and does not converge to a single point, which disqualifies it from being categorized as a prism or a pyramid.
Not all polyhedrons are prisms or pyramids. A polyhedron is defined as a three-dimensional shape with flat polygonal faces, straight edges, and vertices. While prisms have two parallel faces (bases) connected by rectangular lateral faces, and pyramids have a base and triangular faces that converge at a point, there are other types of polyhedrons, such as irregular polyhedra, that do not fit these definitions. Examples include shapes like the truncated tetrahedron or the dodecahedron, which do not qualify as either prisms or pyramids.

No. Polyhedrons are any shape with multiple sides. A triangle and a prism are just two different kinds of polyhedrons.
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.
Triangular prisms and square-based pyramids have 5 faces. Trapezoid prisms and cubes have 6 faces. Hexagonal prisms and octahedrons have 8 faces.
Prisms are a subset of polyhedra (or polyhedrons!)
Polyhedrons are three-dimensional shapes with flat faces, straight edges, and sharp corners, known as vertices. Examples of polyhedrons include cubes, pyramids, prisms, and dodecahedrons. These shapes have a closed surface and are made up of polygons, which are two-dimensional shapes with straight sides.
i am not sure.
No.
Polyhedrons such as pyramids and cuboids
Well, hello there, friend! Prisms and pyramids are like happy little shapes in our geometric world. A prism has two parallel bases that are the same shape and size, while a pyramid has one base and triangular sides that meet at a single point called the apex. Just remember, whether you're working with prisms or pyramids, they both have their own special charm and beauty.
