18 x 10 x 10 inches tank, how many litres?

Question

how many litres or gallons does it hold?

also, how do you work it out?!

Answer 1

If you want the answer in liters. that's the easiest to figure out.

First, convert each of the measurments from inches to centimeters - 1 inch = 2.54 cm, so 18in x 2.54cm/in = 45.72cm Do this for the other two measurements as well.

Second, multiply the three end results from step 1 together to get cubic centimeters (cc). One cc = 1 milliliter (ml)

To convert from ml to liters, divide by 1,000 and that's your answer.

To convert from liters to gallons, 1 gallon = 3.785 liters, so divide the number of liters you get by 3.785.

Of course, lazy people like me don't do the math - we use online calculators and just plug in the measurements:

Answer 2

L(in inches X width(in inches X depth(in inches) = Cubic inches in the tank divided by 231(number of Cubic inches in a gallon) X 3.7854 (number of liters in a gallon). 29.5 l.

Answer 3

18 times 10 times 10 will give you the total cubic inches of your tank (1800 cubic inches)

1 cubic inch equals .016 liters

So, .016 times 1800 will give you 28.8 liters

Answer 4

18x10x10 = 1800 cu. inches

1800/231 cu in.per gal. = 7.8 gal

7.8 gal x 3.78 l per gal. = 29.5 l
