Q.
An ice-cube of density $900\, kg / m ^{3}$ is floating in water of density $1000\, kg / m ^{3}$. The percentage of volume of ice-cube outside the water is
The percentage of volume of ice cube outside the water is
$=\frac{\rho_{\text {water }}-\rho_{\text{ice}}}{\rho_{\text {water }}} \times 100$
$=\frac{1000-900}{1000} \times 100$
$=10\%$
