# How many gallons of water are in the Gulf of Mexico?

ANSWER:The concise Brittanica Encyclopedia estimates the surface of the Gulf of Mexico to be

1,550,000 km2 that is 1,550,000,000,000 m2

e maximum depth of the Gulf is 5203 m.

The average depth is somwhere between 0 and that value. I guess 1/4 the maximum depth (because it gave me an almost round number) of 1300 m.

Multiplying 1,550,000,000,000 m2 x 1300m = 2.015 x 10 E 15 m3 or

5.3 X 10 E 17 USGallons (give or take 1223gallons)

You were pretty close. It's 643 Quadrillion gallons according to the EPA's official site, which says, "... The mean (average) water depth of the Gulf is ~1,615 m and the basin contains a volume of 2,434,000 cubic kilometers of water (6.43 * 1017 or 643 quadrillion gallons)

Yep, you are absolutely correct. I posted the above here and on my blogs, but forgot to come back here and correct my math. I have corrected my numbers above. Thanks for posting your update so that I got an email about this math typo and could correct my numbers above. Study guides Earn +20 pts
