Answer:
60 books
Explanation:
We have to find the least common multiple, wich is a number that is a multiple of all the numbers we have: 2,3,4,5,6
If we start with 2 the multiples will be:
2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60
Multiples of 3:
3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60
With 4:
4,8,12,16,20,24,28,32,36,40,44,48,52,56,60
Multiples of 5:
5,10,15,20,25,30,35,40,45,50,55,60
Multiples of 6:
6,12,18,24,30,36,42,48,54,60
The least common multiple, in this case, is 60 because it is the first number that is a multiple of all other numbers.
So the box has 60 books or a multiple of 60.
