Rabbits that are young like yours aren't going to train (litter train) as easily or as consistently as spayed rabbits (or may lose training with the onset of hormones). They also are going to keep exploring places to dig, chew, and hide in. The idea of clapping only temporarily stops a particular behavior in the moment. Once you aren't there to watch, they will happily go back to their mischief. Rabbits just are not inclined to "please" their human with good behavior the way, say, a dog might.
The best way to avoid destruction of your home, is to block, barricade or remove whatever needs protecting. Bunny proofing is a must, but it looks like you are already on your way to doing that. Chew toys, cardboard boxes, and plenty of hay are all distractions that may help divert bunny's attention for short spurts of time. But barricading, etc is the most effective.
Over the next several weeks she may become more destructive as her hormones become more apparent. This is often the time when frustrated owners decide that fixing would be a good idea. Fixing is done as much for behavior as it is for health. Female rabbits are prone to early cancer when not spayed.
I agree with stevesmum about doing lots of research. As long as I've been keeping rabbits, I still find myself learning new things about them. There is much to learn about these complex cuties.
