Here, the mass of the object =5kg
And, it's volume=500cm^3
=0.0005m^3
now, density =mass /volume
=5/0.0005=10000 kg m^-3
now relative density =density of object/density of water
=10000/1000 ( since density of Water=1000kgm^-3)
=10
thus the relative density of object =10
And, it's volume=500cm^3
=0.0005m^3
now, density =mass /volume
=5/0.0005=10000 kg m^-3
now relative density =density of object/density of water
=10000/1000 ( since density of Water=1000kgm^-3)
=10
thus the relative density of object =10

but,should we not change 5kg into grams first???
no, here it need not change.
