A hole is drilled in a metal sheet. At $\displaystyle 27^{\circ} \mathrm{C}$, the diameter of hole is $\displaystyle 5$ cm . When the sheet is heated to $\displaystyle 177^{\circ} \mathrm{C}$, the change in the diameter of hole is $\displaystyle \mathrm{d} \times 10^{-3} \mathrm{~cm}$. The value of d will be $\displaystyle \_\_\_\_$ if coefficient of linear expansion of the metal is $\displaystyle 1.6 \times 10^{-5} /{ }^{\circ} \mathrm{C}$.
