Nautilus, a mollusk inside a spiral shell, sometimes dives as deep as 400 m below the ocean surface during the day in order to avoid heating by the sun. By what factor is the pressure exerted on the shell at that depth larger than the pressure at 60 m depth, where nautilus usually feeds on plankton? (Note: The density of sea water is ñ = 1030 kg/m³.)
