A slab of stone of area 
and thickness 
is exposed on the lower surface to steam at 
A block of ice at 
rests on the upper surface of the slab. In one hour 
of ice is melted. The thermal conductivity of slab is (Given latent heat of fusion of ice \(\left.=3.36 \times 10^{5} \mathrm{Ng}^{-1}\right)\)
