I do not mean the volume of an object. I am talking about the objects shape (square, sphere, etc.). How does on objects shape effect its density?

On a macroscopic scale there is no measurable effect. On a microscopic level, the spacing between atoms is slightly greater within a very thin surface layer than in the bulk. This effect dimminishes with increased binding energy relative to kT. Objects with a larger surface will have a lower density, but the effect is not significant unless you are studying molecular clusters or nanoparticles.

Object's shape does not change its density.
Making a ship hollow inside will displace more water and help the ship float in water.

Hi. It doesn't. But a ship made out of iron will float because it is hollow (essentially) and a dumbbell will not. Even if the density of the iron is the same.

It does not.
The density of material is mass per unit volume, and is not dependent on shape.

Discounting hollows, ...None
