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
