rushwr · Answer

density = mass divided by volume right ? use that ! For the volume we have to get the volume of iron okai ?

clamin · Answer

how do i do it if i have two volume?

rushwr · Answer

The volume of water contained is given. And the final volume is given too right? So what do we get if we subtract the volume of water from the final volume ?

rushwr · Answer

The difference between the water volume and the final volume is caused by the addition of iron right? So that difference would be the volume of iron ! Hope you got it !

clamin · Answer

3.6 is the difference
