A leak proof cylinder of length 1m, made of a metal which has very low coefficient of expansion is floating vertically in water at 0ºC such that its height above the water surface is 20 cm. When the temperature of water is increased to 4ºC, the height of the cylinder above the water surface becomes 21 cm. The density of water at T = 4ºC, relative to the density at T = 0ºC is close to:
