Pip and Estella know each other to be honest and clever. At the reading of Miss Havisham’s will they see a large crate on which are placed two envelopes addressed V+S+E and V, and a lipstick. The solicitor gives Estella the V+S+E envelope and Pip the V envelope and says, “Inside this crate Miss Havisham has left a cuboidal gold bar whose dimensions in mm are different whole numbers greater than 1, and whose volume, surface area and total edge length are V mm³, S mm² and E mm respectively. Inside your envelope, which you should now open, is the secret value of your address. Every fifteen minutes a bell will ring, and if at that point you know the other’s value, write both values on the crate with lipstick and the gold is yours.” At the first bell Pip and Estella sat still, but when the bell rang again Estella lipsticked 3177 and Pip’s value on the crate.

What was Pip’s value?
