First, you can select 3 publishers from 5 publishers by  C%5B5%5D%5E3 ways.

Then you can can select  4 books from each of the 3 boxes, containing 25 different titles, by  %28C%5B23%5D%5E4%29%5E3 ways.


Compute the mentioned numbers in each of the two lines above, and then calculate their product.


I assume that the ordering of books in the display does not matter

    (since the problem says nothing about it).

You do all calculations, following my instructions.
