Here is the solution:

---------------------------------------

The book is the 18th book from the top

⇒ There are 17 books above it


The book is the 5th position from bottom

⇒ There are 4 more books below it.


Total number of books = 17 before it + the book + 4 books after it

Total number of books = 17 + 1 + 4

Total number of books = 22


Answer: There are a total of22 books
