A physics teacher gave a barometer and asked them to determine the height of the building. A barometer shows atmospheric pressure of a point, where it was measured .The obvious answer teacher was expecting from his students is this: there is a relation between pressure at point and to altitude of the point. At higher altitude atmospheric pressure reduces. So by feeding the observed data to the mathematical formula, which relates drop in pressure to height, you can find the height of the building. Most of the students had done that way. Few students took very clever approach.
