Why do objects float in liquids denser than themselves?

Answer:
Objects sitting in a fluid (liquid or gas) experience a pressure on every surface, equal to the pressure of the fluid. ... If the object is less dense than the fluid, its own weight is therefore smaller than the buoyancy force upwards, and it floats.

hey....
It's not so much that the less dense object floats, it's that the other element - in this case a liquid, is denser (same volume is heavier) and gravity pulls it more strongly to the bottom. Because it is pulled down, it literally displaces the object upward.
So the object does not inherently "float". It simply is less "heavy per volume" than the other medium it is in and which pushes down stronger than object for the same space they would occupy.
hope it helps u dear....
