Thanks, what is given actually is the water displacement of a ship and I must find out the surface area of the hull below waterline. But hull shapes design vary according to vessel application. So what you're saying is surface area can be computed given the water displacement of the hull...
If 2 differently shaped objects are submerged in water, say one is rectangular and other spherical, and both displaces the same volume of water, would the surface area of both objects be the same?
