Answer:
mass=2326kg
Step-by-step explanation:
Archimedes' principle states that when an object is submerged into a liquid, it appears lighter in weight due to the buoyant force applied by the liquid in upward direction. Buoyant force is equal to the weight of the liquid displaced by the object. An object floats on the surface of liquid or floats partially submerged when weight of the displaced liquid is greater than weight of the object.
the mass f he box=74kg
densty=mass /vlme
1000=mass/2.4
mass =2400kg
apparent mass wen completely submerged will be
2400-74kg
mass=2326kg
