A ship made of iron and steel does not sink in sea, but the same amount of iron and steel in form of a sheet would sink Why?

Explanation

A ship has a larger volume as compared to the solid sheet of the same mass. Accordingly, a part of the ship displaces more water than the entire solid sheet and thus experiences more buoyant force and does not sink. One can argue like this also. The average density of an object`=` mass of the object/volume of the object. Since, the volume of the ship is much more than that of the solid sheet of the same mass, average density of ship is less than that of water. Hence, the ship floats. The sheet sinks as its average density is more than water.
