An irregular shaped body of mass 250g is put in a Eureka can and water displaced is collected in a measuring cylinder in which water is already at mark 20 cm³. Now the water level rises to 60 cm³.  The Volume of body is [[1]] cm³ and density is [[1]] kg/m³.

To employ Archimedes' principle, keep in mind the idea of the Archimedes principle and recognize the supplied values. Using the formula for density, calculate the body's density after determining the body's volume, i.e., water rises = the body's volume.

The volume of body V $=$changes in water levels 

$V=60-20=40c{m}^3$

Density of body $\rho =\frac{m}{v}=\frac{250}{40}=6.25gm/c{m}^3$

Also$\rho =6.25\times 1000=6250kg/m^3$

Hence, the correct answer is $40c{m}^3$, $6250kg/m^3$.
