A standard cubic foot of natural gas carries with it about 1.1x 10^6 J of energy. You can get about 1x10^5 BTUs of gas for a dollar and there are about 1030 BTUs in a standard cubic foot. How many Joules of energy can you get for a dollar?

    Let's focus on the units alone first. \[{J \over ft^3} \cdot {BTU \over $} \cdot {ft^3 \over BTU}\]Notice we will be left with J per cubic foot. Can you figure out where you plug in the values?
