A sample of a liquid is kept at $\displaystyle 1$ atm. It is compressed to $\displaystyle 5$ atm which leads to change of volume of $\displaystyle 0.8 \mathrm{~cm}^3$. If the bulk modulus of the liquid is $\displaystyle 2$ GPa, the initial volume of the liquid was $\displaystyle \_\_\_\_$ litre. (Take $\displaystyle 1 \mathrm{~atm}=10^5 \mathrm{~Pa}$ )
