Well it really depends on how many shelves there are.
because we need a number of shelves to figure this out.
depending on how many shelves there is now possible solution because for 2 shelves you would divide 29 by 2 and that gives us 14.5 which is not even a total amount of books because in books 14.5 would mean you could put 14 and a half books on a shelf then the rest on the other shelf the same with 3 shelves and so on threw there.
so sorry to say but thats just how it is
I hope I helped.
