Well One This we can rest assure of is Helium will have a greater mass than a vacuum.

There is no matter in vacuum.

So Coming to The calculation of mass

Mass:

Let the mass of the box be #M_b#

#to## m_1 (he)= M_b + M_h#
And for the one with vacuum

#to##m_2(v) = M_b#

As you can see There is the added mass of helium in box 1

So let me not give you the full answer

Okay hint

So remember density is =#m/v#

And the volume You can take as #1 (kg)/m^3#( This is just for better understanding)--Since volume or the space wont change whatever you have in the box

And another thing you have to remember some thing with a lesser density floats A lot better.This because a liquid has a buoyant force which keeps an object floating

When an object a greater density is place in the liquid it requires more buoyant force.

With the given data you should be able to solve the question of yours
