The basic barometer can be used to measure the height of a building. if the barometric readings at the top and at the bottom of a building are 665 and 695 mmhg, respectively, determine the height of the building. take the densities of air and mercury to be 1.18 kg/m3 and 13,600 kg/m3, respectively. (round the answer to the nearest whole number.)
