Your answer should be in units of cubic feet, not feet (usually written as cu. ft of ft3). When you write exponents, at the very least use ^ to indicate an exponent.

Your numerical answer is way off. Without getting bogged down too much with numbers, let's say for the purpose of a rough calculation that a gallon is equal to 8 cu. ft. Without using a calculator, how many cubic feet would this be? You should be able to do this in your head.

Actually, a gallon is ~1/8 cu. ft.

But, jim1174, do you really think that 8000/7.48 > 100000 ?

I must have written that without thinking very hard. Yes, a cubic foot is about 8 gallons, so 1 gal. ##\approx## 1/8 cu. ft.

ok i think i got it Mark44

ok i think i got it It depends. In your first post you have 7.44 gal./cu. ft in one place and 7.48 gal./cu. ft. in another place. Which is it?

You need to be more careful. I've seen several mistakes like this in your work.
