The question states that the body floats,so,
Weight of the body must be equal to the buoyant force acting on the body
⇒Weight of the body in water =100g
Now,
Weight =mg or actual weight of the object in air
so mg -100=100
⇒mg=200g
∴Its weight in air=200g 
We know that buoyant force =vdg
So,
v×d×g=100
v×1×10=100
⇒Volume of the body is 10g/cc or 10g/cm^3
Hope this helps,sorry if i'm wrong,i don't guarantee this result so ask this to your teacher she will probably be able to solve it.
