The figure shows a U-tube having a $5 \mathrm{~mm} \times 5 \mathrm{~mm}$ square cross-section filled with mercury (specific gravity $=13.6$ ) up to a height of $20 \mathrm{~cm}$ in each limb (open to the atmosphere).

If $5 \mathrm{~cm}^{3}$ of water is added to the right limb, the new height (in $\mathrm{cm}$, up to two decimal places) of mercury in the LEFT limb will be
