    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.

      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.

        Thank you, this helps, brain wrapping successfully now.
