Question

the volume of a plastic covered sealed box is 350 cmcube and the box has a mass 500g. will the box float on water or sink in water? what will be the mass of water displaced by the box?

Answer 1

Given that volume of a plastic sealed box V = 350 cm^3.

Given that mass of the plastic sealed box M = 500 g.

We know that Density d = M/V

= 500/350

= 1.6 g/cm^3.

We know that density of water = 1g/cm^3.

Therefore, Density of sealed box is greater than density of water. Hence, it will sink in water.

Now,

Mass of the water displaced by the box = volume * density of water

= 350 * 1

= 350 g.

Hope this helps!
