In the English version of the Wall of Stone spell the dimension specification of the wall is:
A wall of stone is 1 inch thick per four caster levels and composed of up to one 5-foot square per level.
This would mean for a 9th level wizard I have 9 squared slabs 2 inches thick.
In German this is:
Die Wand ist pro vier Zauberstufen 2,50 cm stark und nimmt eine Fläche von bis zu 1 Würfel pro Zauberstufe mit jeweils 1,50 m Kantenlänge ein.
This would mean I have 9 cubes and can form them into 5 cm thick slabs, which is a huge difference.
The translation (as far as I can see) of the second part would be "one cube with 1.5 m edge length per caster level."
Even though I am quite sure this is wrong, I would like to have this verified since I am not an English native speaker. Since this translation is wrong in all published editions I guess.
