The third grade class collected 148 books to donate to the library the fourth grade class collected 175books the students need pack the books into boxes each box hold 9 books how many boxes do they need to hold in all

They need 36 boxes.

Explanation:

First, we need the calculate the sum of the books collected. That means we have 148 + 175 = 323 books in total. Now we have to find the number of boxes needed. Since in each box they can put 9 books, we need to divide the total number of books by the number of books per box.  

So they will need 323 ÷ 9 = 35.9 boxes

Basically this means that they will need 36 boxes although one of them won't be completely filled with books.
