Question

the volume of a plastic covered sealed box is 350cm3 and the box has a mass 500g

Answer 1

the plastic covered sealed box is 350cm3 band the mass 500g

is the total =500+350=850g3cm3

Answer 2

Answer:

If the density of an object is greater than water (

cm

3

1g

) then that object will sink. If it is less than water's density, then the object will float.

Density=

Volume

Mass

Volume of object = 350cm

3

Mass of object = 500 g

Density =

350cm

3

500g

Density = 1.42

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

Mass of water displaced = Density of Water×Volume

=> Mass of water displaced =1×350=350g
