This is my favorite riddle of all time. I always tell it with relatively easy numbers to add up, since that is not the point. It is, as you know, the way that you are thinking about the problem.
When you are looking at the books sitting on the shelf, you are looking at their spines, so page one is on the right hand side of the book, and page 500 is on the left hand side of the book.
Thus, in your riddle,
the front cover of book 1 is 0.635 cm, then the worm eats through the entire book 2 and 3, adding 0.635, 2.54, 0.635 x2; and then the remaining back cover of book 4, adding 0.635 again.
total amount of cm =8.89 cm

Let's see on a shelf in order, the worm goes from page 1 of book one, through the front cover of book one, into the back cover of book two, the pages of book two, etc etc and stops just inside the back cover of book 4 without eating any pages in either book 1 or book 4.
I don't feel like doing the math, sorry.
Remember a book in a series in order on a shelf will have the front cover on the right side next to the back cover of the next book in the series.

Trivia? I don't think so. You want us to do your homework. You could at least be honest about it.
