I think that there is also a coincident surface as well. Increase the height of
the box by adding a tiny bit to the translate like    translate y*7.51
You don't need a merge unless you are going to add something else to the box and
want to get rid of the internal structure.

When you look at the Statistics in the message window you will see Max Level:
5/5.
That means that the maximum of 5 has been reached. I changed max_trace_level to
25 then PovRay reports Max Level: 11/25

So you can use any value above 10 in your scene.
