When the weight of an object equals the weight of the water displaced (or pushed away) by the object, the object is neutrally buoyant and easy to lift to the surface.
A sailboat sank to the bottom of the ocean. The majority of the boat's weight is from the 0.25\text{ m}^30.25 m

1000, start text, space, k, g, slash, m, end text, cubed. 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 total volume of seawater needing to be displaced in order to lift the sailboat to the surface?
