There are four encyclopedia volumes sitting on a shelf in order from left to right. A bookworm starts eating through the books, starting from the first page of the first book, all the way to the last page of the last book.
If each book cover is 0.2cm wide, and the pages of each book are 5.1cm wide, how far did the bookworm eat?

5.1cm*2 + 0.2cm*6 = 11.4cm
The first page of the first book is toward the other three volumes, as is the last page of the last book. Thus, only the front cover of the first volume and the back cover of the last volume, plus the entire two middle volumes, are eaten through.

Stellar Firefly is right.
When Books are stacked on a shelf left to right, then the cover and the first page is at the right, hence if a book worm wer to start eating from the first page and move towards the next volume, then it would move to the right, hence eating just the front cover of the first volume.
Similarly, the last page of the rlast volumen is towards the left, and hnce the bookworm coming from the left would eat only the end cover last volume.
Therefore the equation is 2 sets of full volumes and 6 sets of covers
i.e. 2 * 5.1 + 6 * 0.2 = 10.2 + 1.2 = 11.4

The answer is 22cm.
the cover of the book is 0.2cm so there are 2 covers in each book so it becomes 0.4cm multiplied by 4 books so the thickness now of all the covers of the book is 1.6cm. then each book is 5.1cm wide multiplied by 4 is equal to 20.4cm, then add the thickness of all cover which is 1.6cm the answer is 22cm.

Since the books were encyclopedia and not cookbooks nor design books or any of that sort, the worm would go as far as 11.4 cm. That is assuming the humidity was average and the temperature was normal, ie, room temp. How the worm got there would still be a mystery, CSI would need to be involved.

Stellar's confusing us all. It says the books are sitting from left to right, and not on top of each other.
One more confusing thing is, the worm eats 6 covers, as it eats from the first page of one book to the last of the 4th (leaving the 2 covers; first & the last; uneaten).
Hence,
(5.1 x 4) + (0.2 x 6) = 21.6cm
Nice question, PINSIR (Y).

Distance lined through malicious software conceal of 1st truly a million area = a million/16 inch pages of vol a million = 2 inches. conceal and pages of two volume. = 2/16 + 2 conceal and pages of three volume. = 2/16 + 2 conceal of 4th volume truly a million area = a million/16 inch pages of vol 4 = 2 inches. entire distance = a million/16 + 2 + 2/16 + 2 + 2/16 + 2 + a million/16 + 2 = = 6/16 + 8 = sixty seven/8 inches = 8 integer 3/8 inches

Very nice, Stellar Firefly. Six covers are eaten through, and only two volumes of pages. Very nice.

He ate until he got to "Spider", then he saw a larger-than-life sized photo of one and it totally freaked him. He passed out and fell off the bookshelf.

for each book cover+pages+cover=0.2+5.1+0.2=5.5
there r 4 boobs so 5.5*4=22.00
therefore ans = 22.0cm

my guess is 20.12 cm, but I really have no clue.
