Since the volume of the cube = 1000 cc, the volume of water displaced by it (under the given condition) = 500 cc. Since water has a Specific Gravity of 1 The weight of water displaced will be 500 gram. This is precisely the force of buoyancy acting on the cube. Hence a weight of 500 gram or less can...

Assumption: The cube sinks to half its height due to its self weight volume of 10 cm cube is 1000 cm3 half vol. = 500 cm3 normal density of water = 1000 kg/m3 mass of water that can be displaced = 0.5 kg weight that can be supported by such displaced water = m*g assuming gravity = 9.8 m/s2 weight...

By theorm, "weight of body = weight of water which is replaced by body " So, weight of water replaced by body =(10 x 10 x 10 ) x10 / 2 = 5000 kN then, 10 x 10 x 10 x unit weight of body = 5000 ( by theorm) then , unit weight of body = 5 kN / m3 for body not sink , if body...
