Whenever an object (or substance) can displace an amount of
liquid equal to its own weight, it’s able to float. This displaced
water pushes up against the object, in effect keeping it
afloat. This upward force is called bouyancy. If it can’t
displace an equal amount of water, then there won’t be
enough bouyancy force pushing up to counter the downward
weight of the object. When this happens, the object sinks.

You have to remember, that density is not the only reason why objects float. The ships have details that have much harder density, and they float because of the position they have in water. But fill them with water and they'll sink. The laws of physics "work" here as well!

determine the apparent volume of the object and its weight. The volume will b dependant on how you view it but for example a concrete boat will float if the volume is correct,(including the void). Determine the apparent density by dividing weight by apparent volume. If it is less than the density of water used it will float.

Calculate the amount of water that it will displace. Convert that number to weight. Compare the weight of the water to the weight of the object. If the object is lighter, it will float.

By measuring the volume of the object and weighing it. If it is less dense than water, it will float.

By the AREA of an object and how much water it will DISPLACE. (The weight is a secondary concern...) The larger the AREA of the object, the greater amount of water it will displace, hence..., the propensity for it to float.

Placing it in a liquid with EXACLTY the same density as water is the only 100% sure way.
Any calculations you do based on mass will hold minute errors due to not using exact figures so may be wrong

check its density-per centimetre cube or per cc and if its lesser than water's,which is 1 g/cc , then it will surely float
now if its density is very lower than water's than it will float with a major part of its body above water
or else most of its body will be submerged in water and it will float like that
any other questions-call me!

One would recognize if an merchandise will opt for the flow by skill of understanding what's the composition of the article. Then one would opt for to calculate the density of H2O (water), it truly is a million gram in accordance to a milliliter. verify with a table of Periodic table that would help you recognize the density of the article. ---- also ---- gadgets would also opt for the flow on water if it might want to displace its weight on water. it truly is how massive ships opt for the flow atop of water. Weight displacement.

count its density by dividing its mass with volume and if it is less than the density of the water than it will float
