A slab of stone area 3600cm^2 and thickness 10cm is exposed on the lower surface to steam at 100^\circ C A block of ice at 0^\circ C rests on upper surface of the slab. In one hour 4.8kg of ice is melted. The thermal conductivity of stone in Js^{-1}m^{-1}k^{-1} is (Latent heat of ice =3.36\times10^5J\text{/}kg)
