how about it is in a cube shape?

Both has the same weight 1kg. THe volume of both differs , cotton is more in volume. But both are equally heavy of 1kg weight each.

Based on the concept of physics, they both weigh the same...
1kg=1kg
But if you asked 3 m^3 of cotton with 3 m^3 of iron...that's a different story...

According to conventional physics, they both weigh the same. However, if the theory of the fifth fundamental force is proved accurate, the 1kg of iron would drop marginally slower than the 1kg of cotton in a vacuum, and so you could say that 1kg of iron weighs marginally less than 1kg of cotton.

Their weight is same but if they are dropped from a height, the iron will land first compared to cotton since the volume and hence the buoyancy of the cotton will be higher, unless the cotton is highly compressed so that its density is sufficiently high. Fluffy cotton will take a lot of time to fall because of the buoyancy provided by the air.

As it has already been pointed out, they are the same weight. But if you actualy weight them, 1kg iron will be heavier. This is due to the buoyancy force in air. Cotton has lower density and therefore, the buoyancy force is larger on that one. So, the answer is not realy that obvious.

It depends where you measure my friend.
Since Kg is the unit of mass and you asked which is heavier(that means considering the weight).
If your iron be on teh moon and your cotton on earth, then the cotton would be heavier than the steel.
cause 1kg cotton gives 9.81 N downward force(on earth) but your 1 kg iron generates only 1.635 N downward force(on moon).So for measuring which one is heavier,you should say if the " g "(s) applied to both are the same.
If they undergo a same g, then both have same weights.but if their g differs,then their weights would be different too.
Hope you the answer got your tricky physique-concepts based question.
Good Luck!

They are of equal weight. 1 kg = 1kg. Assuming they are under similar environmental factors.

1 kg of iron weighs less on Mars than 1 kg of cotton on Earth

The both way the exact amout it wuold be like asking what weighs more a ton of bricks or a ton of paper the both weigh the same amount

they're both one kilogram so they have the same weight, they differ in quantity though since a piece of iron is heavier than a piece of cotton if they are of same size
