A glass flask contains some mercury at room temperature. It is found that at different temperatures the volume of air inside the flask remains the same. If the volume of mercury in the flask is 300 cm${}^3$, then find the volume of the flask. If your answer is $N$ (in cm${}^3$). Fill value of $\frac{N}{250}$. [Given that coefficient of volume expansion of mercury and coefficient of linear expansion of glass are $1.8\times 10^{-4}{(}^{\circ }$C${)}^{-1}$ and $9\times 10^{-6}{(}^{\circ }$C${)}^{-1}$ respectively]
