The gauge pressure at a depth of 6 cm in a glass filled with 4 cm of mercury and 4 cm of water is 3.1 kPa. This is because the pressure due to the mercury is 4 cm * 13.6 * 9810 N/m^3 = 54944 N/m^2, and the pressure due to the water is 4 cm * 1000 kg/m^3 * 9.81 m/s^2 = 3924 N/m^2. The total pressure is therefore 54944 N/m^2 + 3924 N/m^2 = 58868 N/m^2, which is equivalent to 3.1 kPa.
