Explanation:
The relation between power, current and voltage is
Applying the given values in the relation above we get
Now Since 
Again applying the calculated values we get
Hello there! With the values of density and volume, you would be able to find the object's mass.
Density is found by dividing the mass by the volume, so you could place in the values of the density and the volume to get the mass.
For example:
500 = mass/10
The 500 being density and 100 being volume. You would use simple math rules and multiply 10 by 500, and you'd get 5000, therefore using the density and volume values and giving you the mass.
I hope I could help you and have a great day!
