A man and his wife clean their teeth from the same cylindrical tubeof toothpaste on alternate days. The interior diameter of the nozzle through which the paste is squeezed is .08 of the diameter of the tube,which is 3.4 cms. If the man squeezes out a cylinder of toothpaste 1.82 cms in length each time he uses it, and his wife a cylinder 3.13 cms in length, find the length of the tube to the nearest mm, if it lasts from the 3rd of January to the 8th of March inclusive and the man is the first to use it.
