Density = Mass/Volume

Now,
For the sealed tin

Mass= 250 g
Volume= 400 cm³

So,

Density=Mass/Volume
            =250/400
            =0.625 g/cm³

Now, we know  that density of water is 1000 kg/cm³ or 1 g/cm³

As the density of the sealed tin is less than the density of water, it will float.   

It can be done by method as follows:

Specific Gravity (Relative Density with respect to water) = Density of sealed tin/Density of water
 
=0.625/1
=0.625

Thus the specific gravity of the sealed tin is 0.625 

So it floats on water.

Density of object = mass/volume So density = 250/400 Density =0.625g /cc As we know that the density of water is 1g /cc so the weight of object is lesser as compared to the density of water hence it will float.
