  • A uniform solid cylinder of density floats

A uniform solid cylinder of density 0.8 \mathrm{~g} / \mathrm{cm}^3 floats in equilibrium in a combination of two non-mixing liquid A and B with its axis vertical. The densities of liquid A and B are \mathrm{0.7 \mathrm{~g} / \mathrm{cm}^3} and 1.2 \mathrm{gm} / \mathrm{cm}^3. The height of liquid A is \mathrm{h_A=1.2 \mathrm{~cm}} and the length of the part of cylinder immersed in liquid B is \mathrm{h_B=0.8 \mathrm{~cm}.} Then the length of the cylinder in air is
