In your case, you'll want to use Round_Box_Union. The difference between
Union and Merge is:

Union: Will group the objects together but each object will still retain its
surface.
Merge: Will "melt" the objects together and remove surfaces.

Think of "union" as a grouping tool and "merging" as a melting tool. If all
of your objects are opaque, as they are in your case, you can use "union"
because you won't see the surfaces of the cylinder, spheres, and boxes that
make up the cube. However, if your cube was made of glass, you would see the
cylinder, spheres, and boxes that make up the cube unless you chose to melt
them together using "merge".

Note that, as you probably guessed, merge takes longer to render because of
the extra work it has to do. So, use union whenever you can get away with
it.
