    Incidently the number of volumes in the Transum Encyclopedia and the thickness of the pages changes each time this page is refreshed so it'll be a different answer next time you visit."

Answers

The answer is 25.4cm

Did you realise that the front cover of volume one is on the right side of the book, so the worm only chews through the front cover of volume one before starting on volume two?

The meal consists of: The front cover of volume one plus six times the thickness of a complete volume plus the back cover of volume eight.

4mm + 6 x 4.1cm + 4mm
