Answer:

There are total 30 books in the 5 feet high stack of books.

Explanation:

The complete question is

Given, Each note book is 2 inches thick, How many notebooks do you think it would take to make a stack that is 5 feet high

Solution

Thickness of each book
= (2)/(12) = (1)/(6)

The total height of the book stack is
feet.

The number of books in the stack is equal to total height of the stack divided by the thickness of one book

Number of books in five feet high stack is

$(5)/((1)/(6) ) \\5 * (6)/(1) \\30$

Hence, there are total 30 books in the 5 feet high stack of books.
