i think about 5929 ways
5.This question is the same as asking how many factors does 18 have.18 has the following factors:1, 18, 2, 9, 3 & 6.Therefore you could pile the books 6 different ways.However, as the question says equal piles (plural) then I think we should probably discount 1 pile of 18 books, so the answer is 5.
Oh, dude, stacking books is so last season. But if you really wanna know, the number of ways you can stack 77 books in a pile is like... a big number. It's actually 77 factorial, which is like 1.4518309202828583e+113. So, good luck with that, I guess.
Add all the books and divide by 4: 18 + 19 + 24 + 23 = 84; 84 divided by 4 = 21 books per stack

yes there are many photos if you look on google images, books and history websites.
Use the factors of the number. Factors of 10 are... 1,2,5 & 10. Therefore they will stack either in 1 row of 10 books or 2 rows of 5.
