In an experiment to determine the velocity of sound in air at room temperature using a resonance tube, the first resonance is observed when the air column has a length of $\displaystyle 20.0$ cm for a tuning fork of frequency $\displaystyle 400$ Hz is used. The velocity of the sound at room temperature is $\displaystyle 336 \mathrm{~ms}^{-1}$. The third resonance is observed when the air column has a length of \_\_\_\_ cm
