There are only four different configurations.
Ignoring rotations, there are 3 distinct solutions.

You can make four.
There are only four different configurations.
You could try 14!
Well, honey, if the height is 4 cubes, that leaves you with 12 cubes to work with for the base. You can arrange those 12 cubes in various ways to form different rectangular prisms. So, technically speaking, there are multiple rectangular prisms you can create with 48 cubes and a height of 4 cubes.

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.

With no repetition of shapes (symmetry) we have obtained 26 different combinations.
The answer depends on the number. Note that the question does not require the solids to be in the form of cubiods (rectangular prisms).
