A parallel plate capacitor has plate area $100{ \mathrm{m}}^2$ and plate separation of $10 \mathrm{m}$. The space between the plates is filled up to a thickness $5 \mathrm{m}$ with a material of dielectric constant of $10$. The resultant capacitance of the system is ‘x’ pF .  The value of ${\epsilon }_0=8.85\times {10}^{-12}{\mathrm{F}.\mathrm{m}}^{-1}$ 
The value of ‘x’ to the nearest integer is ________.
