SUMMARY

A cubic foot is defined as 7.48 gallons, which is crucial for converting tank volumes. In the discussion, a tank with a volume of 8000 gallons was incorrectly calculated to hold 107,527 cubic feet using the wrong conversion factor of 7.44 gallons per cubic foot. The correct conversion should use 7.48 gallons per cubic foot, leading to a more accurate calculation of approximately 1,067.5 cubic feet. Participants emphasized the importance of consistency in conversion factors to avoid significant errors in calculations.

Homework Statement


2. A cubic foot is equal 7.48 gallons. How many cubic feet will the tank describe in question #6 hold?

Homework Equations

The Attempt at a Solution



Tank has a volume of 8000 gallons.

1 feet3 = 7.44 gallons (given)

Therefore,

8000 gallon = 8000gallon x feet3/7.44gallon= 107527feet

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

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.
