Given that volume of a plastic sealed box=> V - 350 cm^3.
Given that mass of the plastic sealed box=> M 500 g.
▶Density M/V=> 500/350 => 1.6 g/cm^3.
▶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
=>350g...Ans..✔

Answer:
If the density of an object is greater than water ( 1 g / cm³ ) then that object will sink. If it is less than water's density, then the object will float. Hence 1.42 > 1.
