In Oracle database, dropping a table don't free up the space directly. You'll need to disabled the DB recycle bin. So whenever we drop something, it's purged automatically to free the space.

And another minor suggestion about searching Oracle doc on Google. Add 112 to show 11g release 2 doc on top.
