Henry Ernest Dudeney/Modern Puzzles/190 - Packing Cigarettes

by : $190$

 * Packing Cigarettes
 * A manufacturer sends out his cigarettes in boxes of $160$;
 * they are packed in $8$ rows of $20$ each, and exactly fill the box.
 * Could he, by packing differently, get more cigarettes than $160$ into the box?
 * If so, what is the greatest number that he could add?


 * At first sight it sounds absurd to expect to get more cigarettes into a box that is already exactly filled,
 * but a moment's consideration should give you the key to the paradox.
