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

In cubic meters, what is the total volume of seawater needing to be displaced in order to lift the sailboat to the surface?
