You can have the 18 as prisms, OR.. they can be cut up into an infinite number of different prisms, as many as your tools for cutting it can make.
Just one, although the orientation of the prism might vary.

They are all called cuboids or hexahedra. There are no names that give more details about the prisms' structure.
2 cubes = 4 prisms
You can have the 18 as prisms, OR.. they can be cut up into an infinite number of different prisms, as many as your tools for cutting it can make.
There are only four different configurations.
Ignoring rotations, there are 3 distinct solutions.
Four.
Three.
The answer depends on the number. Note that the question does not require the solids to be in the form of cubiods (rectangular prisms).
Just one, although the orientation of the prism might vary.

There are many options: 2 rectangular prisms 2 cubes 2 parallelepipeds 2 tetrahedrons 2 square based pyramids are some possibilities using convex polyhedra.
