Explanation:

Given : A stack of books is 5 feet high of the average book is 3 inches High.

To Find: How many books are in the stack?

Solution:

1 foot = 12 inches

`12 * 5 = 60` inches

Height of stack = 60 inches

Height of 1 book = 3 inches

=
`(60)/(3)`

=
`20`

Hence,There are 20 books in a stack.
