The volume of a plastic covered sealed box is 350 cm3 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?
Volume of box = 350 cm3
Mass of box = 500 g
Density of object = `"Mass of Object"/"Volume of Object" = 500/350` = 1.43 g/ cm3
Now, we know density of water = 1 g/cm3
Since, density of box > density of water, therefore the object is going to sink in water.
Now, volume of liquid displaced = Volume of the object = 350 cm3
⇒ `"Mass of liquid displaced"/"Density of liquid displaced" = 350 "cm"^3`
⇒ Mass of liquid = 350 × 1 = 350 g
