The ship, Queen Elizabeth 2, was a cruise ship from 1969-2008. She currently resides in Mina Rashid, Dubai as a floating hotel. When fully laden she held 70,327 tonnes and therefore displaces that weight of fluid when afloat. If the the density of seawater is 1024 kgm-3, calculate the upthrust exerted on the ship when she was afloat fully laden. g = 9.81 NKg-1
