On the shelf stand volumes 1, 2, and 3 of the first edition of Soseki's I Am a Cat. The books have been lying there for a long time, and moths have dug a tunnel from page one of volume 1 to the last page of volume 3. The paper in each volume is 3 centimeters thick and its cover is 1 centimeter (front and back covers are 5 millimeters each). Can you tell how long the tunnel is?
