If a cube whose volume is 8000 cm3 and a mass of 16000 kg is under water what is the weight of the cube?
Archimedes' principle: an object in water experiences an upward lift equal to the weight of the volume of water being displaced.
volume of water displaced = 8000 cm3
weight of water displaced ~ 1 g/cm3 at room temperature and sea level
weight of cube in air = 16000 kgf
lift ~ 8000 gf = 8 kgf
weight of cube in water = 16000 kgf - 8 kgf = 15992 kgf

Is it true that If an object floats the volume of the displaced water is equal to the volume of the portion of the object that's underwater?
the weight of the displaced water is equal to the weight of the object
How much does a 10 pound brick weigh underwater?
That depends on the volume of the brick. Whatever its volume is, its weight underwater is(weight of the brick in air) minus (weight of an equal volume of water)
How much weight is 120 cubic centemetres?
cubic centimetres is volume not weight. if it is water then it would weight 120 grams
Specific weight of water?
Specific weight is the weight of the material per unit volume. Water has the specific weight of 62.43 pounds per cubic foot or 9.807 Newtons per cubic meter.
Does one gram weight equals 1 ml volume?
Only if it is water, which has a mass of 1gram per ml volume
