There are 20 books in the stack.
Given that
A stack of books is 5 feet high.
If the average book is three inches high.
We have to determine
How many books are in the stack?
According to the question
A stack of books is 5 feet high.
If the average book is three inches high.
Firstly convert 5 feet into inches.
[tex]\rm = 5 \ feet \times 12 \ \\\\= 60 \ inches[/tex]
Therefore,
The number of books in the stack is,
[tex]\rm = \dfrac{Size \ of \ stack}{Size \ of\ books}\\\\= \dfrac{60}{3}\\\\= 20[/tex]
Hence, there are 20 books in the stack.
