Asailboat sank to the bottom of the ocean. the majority of the boat’s weight is from the 0.25m^3 of lead in its keel. the density of lead is approximately 11,000 kg/m^3 . the density of seawater is approximately 1000 kg/m^3 . because gravity is pretty much the same everywhere on earth, the weight of the sailboat can be assumed to be approximately equal to its mass. in cubic meters, what is the volume of seawater needing to be displaced in order to lift the sailboat to the surface?
