Two wedges each of mass $600 \mathrm{~g}$ are placed next to each other on a rough horizontal surface. The coefficient of static friction between the wedges and the surface is 0.4 . A cube of mass ' $M$ ' is balanced on the wedges as shown in the figure. If there is no friction between the cube and wedges, the largest mass ' $\mathrm{M}$ ' of the cube that can be balanced without motion of the wedges is ____ $\mathrm{kg}$
