Total is 4 hours
Average thickness of book = Total thickness/mo. of books

= 2.8 cm
Thus, on average, each book has 2.8 cm thickness.
Let the third side = x.
The sum of any two sides must be greater than the third side
14 + 9 > x
23 > x
14 + x > 9
x > -5
9 + x > 14
x > 5
So 5 < x < 23
13cm is the answer i hope this helps you!!!!!!!
