What part of Czechoslovakia did Hitler demand?

Hitler believed that there was a vast majority of Sudeten Germans in the Sudeten Land, and that by taking over it he was only complying with Wilson's idea of self-determination. He also thought that if in a later war he were to be attacked by the Russians that it would act as a first line of defence. Also by taking over Czechoslovakia he would be that one step closer to Poland and his policy of expanding East.
