Can somebody convert this for me please?

Question

18"x18"x24" tank. I want to know how many gallons that is.

Thanks!

Also can you please tell me how you did it? (website maybe?)

Answer 1

(18 in)(18 in)(24 in) = 7776 cubic inches
(7776 cubic inches)(1 gallon /231 cubic inches) = 33.66 gallons

So the tank is 33.66 gallons.

Answer 2

First, you need to know the units before you even put in the numbers.

Volume of a tank = l*w*h = (inches)(inches)(inches) = cubic inches.

Next, need the conversion factor to go from cubic inches to gallons:

1 gallon = 231 cubic inches.

Now, we need to find out how to get from cubic inches from gallons:

cubic inches -> gallons

cubic inches*{(gallons)/(cubic inches)} = gallons

So, first, we calculate the number of cubic inches in the tank:

V = lwh = 18*18*24 = 7776 cubic inches:

7776 cubic inches*{(1 gallon)/(231 cubic inches)}

= 7776 gallons/231

= 33.7 gallons

Answer 3

Multiply the three terms together and divide by 231 (number of cubic inches per gallon).

Answer 4

1 gallon is defined as 231 cubic inches, so:
18x18x24=7776 cu in = 33.66 gallons

Answer 5

You can calculate the volume in cu. inches. It is = 7776 cu. in.

Converting this to cubic feet ( 1 cubic foot = 12" x 12" x 12" = 1728 cubic inches ) , we get 4.5 cu. ft.

Now to convert to gallons , there are various gallons !

You have the British gallon , the U.S. gallon for dry material , and U.S. gallon for liquids. The conversion factors are different for each of these.

For conversion to British gallon :

4.5 cu. ft. = 28.0297 U.K. gallons

For conversion to U.S. gallon ( liquid ) :

4.5 cu. ft. = 33.7 U.S. gallons ( liquid )

For conversion to U.S. gallon ( dry ) :

4.5 cu. ft. = 28.9 U.S. gallons ( dry )
