So, I did the math, assuming that the tractor trailer was filled to capacity, because it didn't state that exactly how much gold was in there. I calculated the volume of the trailer, which came out to roughly 337.5 cubic feet. Then, I multiplied that by 1,204 lbs, the weight of one cubic foot of gold, which gave me 406,350 lbs of gold. Divided that by 16 to make 25,396.87 ounces. Multiply that by the our current value of $1,302 for ounce, and I came to the astounding conclusion that Jax is sitting on over $33M worth of metal.
I'm not quite sure that the trailer could even hold 400,000 pounds, but hey, sci-fi! Also, I always just assumed that all currency in the SARP universe was pretty much equal in value to the American dollar.
Did I screw up anywhere?
