Question

the volume of a plastic covered sealed box is 350cm3 and the box has a mass 500g will the box float on water or sinl in water ?what will be the mass of water displased by the box

Answer 1

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.

Density = Mass / Volume

Volume of object = 350 cm³

Mass of object = 500 g

Density = 500 g / 350 cm³

Density = 1.42 g / cm³

Hence 1.42 > 1. This implies that the object will sink.

Mass of water displaced = Density of Water * Volume

=> Mass of water displaced = 1 g / cm³ * 350 cm³ = 350 g

Hence mass of water displaced = 350 g.

Answer 2

Answer:

the plastic covered sealed box will sink in water
