Henry Ernest Dudeney/Modern Puzzles/142 - Economy in String

by : $142$

 * Economy in String
 * Owing to the scarcity of string a lady found herself in this dilemma.
 * In making up a parcel for her son, she was limited to using $12$ feet of string, exclusive of knots,
 * which passed round the parcel once lengthways and twice round its girth, as shown in the illustration.
