Want this question answered?
It could way less, it could way more, or it could way the same. Depends on the pressure. If the pressure is the same in both cubic meters, then the hydrogen ways less than the oxygen.
Different types of wood come in different densities; most types of wood have a density slightly less than that of water (which has 1000 kilograms per cubic meter), some (like balsa) have quite a lot less, and there are even types of wood that sink in water.
Probably only 1, or less than 1, unless they are very small trees.
No way of telling, as plastic can come is several different densities. Plastic is a generic term for lots of synthetic (artifically created) substances. Its density, however, is quite often less than the density of water, which has a density of one ton per cubic meter.
The volume of 4 meters by 2 meters by 12 centimeters is 4 meters x 2 meters x 0.12 meters, or 0.96 cubic meters. That's just a bit less than a cubic meter.
less ... much less more than 27 cu ft in one cu meter
Anything less than that of 1 cubic meter? Many things...

When it is at a lower pressure or a higher temperature.
At the top, because the pressure there is lower.
well air is thinner at higher elevations so i would say less at the top...
It will float if its total density is less than that of water (1000 kg / cubic meter).

It isn't. Volume and mass are two very different things. Of course, depending on the units chosen, and the material that takes up a certain space, volume may be less than mass in some cases. But, to give a counter-example: in a perfect vacuum, a cubic meter has a volume (in SI units) of 1 (cubic meter), and a mass of zero (kilograms).It isn't.

Density varies - in cold, denser areas there may be as many as 10^12 molecules per cubic meter; in hotter less dense areas, about only 100 ions in the same volume. One source puts the average at one million atoms per cubic meter. Compare to about 10^25 molecules per cubic meter for air.
Probably only 1, or less than 1, unless they are very small trees.
A tonne of what? If we assume wood, then the tonne of wood would be larger - wood is less dense than water.
