How much space is taken up by the carbon dioxide emissions created from a single gallon of gasoline?

How to fill two Ford Explorers with a single gallon of gasoline
Punching a few keys on our wristwatch calculators yields a solution:
Volume = (201.7 x 0.082058 x 277.6)/1 = 4,594 liters Huh? Not a very useful number. So let’s break it down a different way. That’s the same as 162 cubic feet of emissions, which is what you’d get if you had a cube that was 5 and a half feet on each side.

Or how about this way: 162 cubic feet is roughly twice the cargo capacity of a Ford Explorer. You could pack two Ford Explorers full with the carbon dioxide emissions from a single gallon of gas.

Now you know. You get angry in traffic and punch that V8 and blam, pretty soon there goes another 162 cubic feet of CO².
