Because they each weigh 300 pounds, they weigh the same, thus neither is heavier than the other.

Two pounds of feathers are heavier than one pond of steel, but the feathers are less dense than the steel so two pounds of feathers have a greater volume than one pound of steel. Density determines weather an object will float or sink. If an object can float on water it has to be less than 1. If the object is more dense than water than it will sink.
a pound of anything weighs the same, a pound!!
