Assuming you mean size, no: The iron is more dense, so there is less material to match the double-weight of the wood.
Not sure if this is a serious question but...A kilogram is a unit of mass, or in this case, weight.A kilogram is a kilogram.One kilogram of anything is a kilogram.1 kg of iron = 1 kg of wool.
same weight
The weight of a body in air is its apparent weight because the body body remains immersed in air . Therefore apparent weight of 1kg cotton and one kg iron is same .But volume of 1 kg cotton is greater than the volume of 1 iron
They both weigh the same = 1KgThe answer is there in your question
They both weigh the same, 1 kg
1 kg of lead has more volume And that's because lead is more dense than copper. A given volume of lead weighs more than that same volume of copper. It turns out that 1kg of something will weigh the same as 1kg of something else, though the two may have different volumes for that weight.

iron
They both weigh the same: 1kg = 1kg. The kg of butter has a greater volume and the kg of lead has a higher density.
they are the same... they are both 1kg
The lead and the copper will weigh the same. But there will be less lead than copper by volume if both materials are solids. And that's because lead is more dense than copper. A given volume of lead weighs more than that same volume of copper. It turns out that 1kg of something will weigh the same as 1kg of something else, though the two may have different volumes for that weight. A kg of lead takes up a lot less room (volume) than a kg of ping pong balls, even though they both weigh the same.
Without knowing the density of an object, it's not possible to calculate it's volume by weight. A 1kg piece of granite and a 1kg piece of igneous rock would be very different in volume.
