Question

calculate the density of an object of volume 3m cube and mass 9kg state whether this object will float or sinte in water give reason for your answee​

Answer 1

Answer:

The object will float in water

Explanation:

It is simple.

you need to only compare the density of each liquid to know that will it float or not.

in this case water density at room temp. is 997kg/m^3 and the dencity of substance above is only 3kg/m^3.

as the density of water is more and the density of substance is less.The substance will float on water.

And remember the formula for density is mass(in kg)/volume(in m^3)
