A cubical block of ice floating in water has to support a metal piece weighing 0.5 kg. Water can be the minimum edge of the block so that it does not sink in water? Specific gravity of ice = 0.9.
Specific gravity of ice, ρice = 0.9 gm/cc
Weight of the metal piece, m = 5 kg
Density of water, = 103 kg/m3
Let x be the minimum edge of the ice block in cm.
mg + Wice = U
U = Upward thrust
Wice = Weight of the ice
