But shouldn't the answer to the one with the kilograms be metal? Because kilograms is a measure of mass, not weight. And then asking which one is heavier is asking about weight and not mass, and weight is a measure of force requiring gravity and lots of other things to be considered...because something can have less mass than something else but still be heavier.
