Question

. The volume of a plastic covered sealed
box is 350 cm' and the box has a mass
500 g. Will the box float on water or
sink in water? What will be the mass of
water displaced by the box?​

Answer 1

Answer:

The box will sink in water, and would displace 350 gram or 0.3 kg of water.

Explanation:

First we should find the density of the box, which equals to mass of box divide by its volume. If the density of box is greater than that of water then it would sink (as in this case) otherwise it would float on surface.

The mass of water displaced can be determined by finding the volume of water displaced first and then convert it into mass of water by the relation that:

$1liter = 1000cm ^{3} = 1kg \: of \: water$
