An iron box which is filled with vaccum inside will folat or sink in water?

Expert Answer

Dear student,

It actually depends on the dimension of box.Let us say the dimensions are large enough,then weight of liquid displaced is large enough to be equal to that of box and it will float.On the other hand if dimensions are small than enough water might not be displaced to make the box float.
