Fun with algebra COVERED IN OIL.

Posted by on October 8, 2008

According to my admittedly dubious calculations, the oil drop depicted on the cover of this book would satisfy our current(actually 2005) oil consumption for over 7 million years.


1 mi = 5280 feet
1 cu foot = 7.48051948 US gallons
1 oil barrels = 42 US gallons
Total World Petroleum Consumption(2005) = 83,607,000 barrels/day
Surface area of Guatemala = 42,042 sq mi

Assumptions(here we go):
the drop looks about the size of the Central American country pictured in green near it. I think that’s Guatemala. I assumed that the drop has about as much volume as Guatemala if Guatemala were a box with (length * width) equal to Guatemala’s surface area and depth equal to Guatemala’s approximate east-west width (I figure it at about 200 mi).
So it’s a 200 mi by 42042 sq mi volume.

PHEW! That was easy.
