In a hydraulic lift, the surface area of the input piston is $\displaystyle 6 \mathrm{~cm}^2$ and that of the output piston is $\displaystyle 1500 \mathrm{~cm}^2$. If $\displaystyle 100$ N force is applied to the input piston to raise the output piston by $\displaystyle 20$ cm, then the work done is $\displaystyle \_\_\_\_$ kJ.
