Density is mass/volume

You've given 3 dimensions of an object, does that mean that it's a rectangular solid? If so, then vol = L*H*D.

Your mass to weight conversion does not compute - at least not if the object is on earth. 210 g weighs about .46 pounds.

Straighten that out and density is m/volume or w/volume (depending on which system you want to be in).

256.41 kg/m^3
as density = mass/volume
