At standard temperature and pressure (STP) it looks like CO2 has a density of 1.96 kg/m^3. 1 tonne = 1000 kg, so a tonne of CO2 has a volume of (1000 kg)/(1.96 kg/m^3) = 510 m^3 at STP. A cube of that volume would have side length (510 m3)(1/3) = 7.99 m, so roughly 8 meters per side.
I don’t know how tall that person is, but if we assume around 1.6 m (5’ 3") then the cube side length should be about 5 of her. Seems pretty accurate to me.
My brain is not wrapping around this so well.
The co2 in that cube at normal air pressure would weigh 1000 kg?
Doesn’t air only weigh a kilogram per cubic meter?
I know co2 is heavier, but is co2 that much heavier?
Like 20 times heavier?
No, I just looked it up, air is 1.2 kg per cubic meter and CO2 is 1.8 kg per cubic meter.
Someone set me straight, I don’t get it.

Thank you, this helps, brain wrapping successfully now.
