The coefficient of real expansion of mer...

The coefficient of real expansion of mercury is `18 times 10^(-5@)C^(-1)`. A thermometer has a bulb of volume `10^(-6)m^(3)` and the cross-section of the stem is 0.002 `cm^(2)`. Assuming the bulb to be filled with mercury at `0^(@)C`, find the length (in cm) of the mercury column at `100^(@)C`.
