Question

Calculate the mass of a body whose volume is 3 m^3
and relative density is 0.75.
[Ans. 2250 kg]​

Answer 1

Explanation:

relative density=density of body/density of water

0.75=d/1000kg/m^3

Thus, density of object= 0.75× 1000kg/m^3

= 750 kg m^3

Mass= density× volume

= 750kg×3

= 2250kg/m^3
