The pressure in a water pigeon the ground floor of a building is4×10fifth pa but three floors up it is only 2×10fifth pa. What is the height between the ground floor and the third floor? The water pipe may be assumed to be stationary density of water is1.0×1.0cubed kg/m cubed

You mean water density = 1 * 10^3 kg/m^3
p lower = p upper + rho g h
(4-2) 10^5 newtons/m^2 = 1000 kg/m^3 * 9.81 m/s^2 * h
h = 2 * 10^2 / 9.81 = 200/9.81 = 20.4 meters (I doubt it)
