I know that density matters, but does the shape of an object make a difference in floating or sinking?

Yes! A flat, wide object can displace more water, which increases buoyancy.

Think of a concrete block versus a concrete boat. Shape changes everything.

That’s why boats are designed with hulls that maximize water displacement.
