1.184 kg is about 2-1/2lbs so that can't be right. Definitely not 396.9lbs.
Edit: sorry I thought it was foot not metre. The 1.184kg could be correct.

Interesting. If you filled a balloon with one cubic meter of air and put it on a scale, then subtracted the weight of the balloon, you'd have your answer. In terms of "weight."
At that point, I would begin to wonder whether the "mass" of the balloon would be different from its "weight."
