The librarian should be able to get 360 books on these 6 shelves which are 10 feet long.  First you multiply 12 inches by 10 feet.  That gives you 120 inches.  Multiply 120 inches for each shelf by 6 because you have six shelves.  This will give you a total capacity of 720 inches.  Divide 720 inches by 2 inches which is the approximate size of the books.  This will give you 360 books.

Since a shelf is 10 feet long and each book is 2 inches long, convert feet to inches before finding the result.

 1 foot = 12 inches

6(10*12)/2

 6(120)/2

3(120)

360 books

Multiply 10 feet by 12 inches to get 120 inches

Since you have six shelves, multiply 120 by 6 to get 720 inches.

Since each book is about 2 inches tbick

amt. of book= 720/2= 360 books

Simplest solution: 

If a book is about 2 inches,

Then there are about 6 books per foot x 10 feet per shelf x 6 shelves

= 360 books!
