2000 liters = about how many gallons?

Are you using U.S. gallons or the old Imperial gallons in your conversion?

1 U.S. gallon = 3.785 litres

1 Imperial gallon = 4.546 litres

i am using U.S. gallons

my teacher said that 1 liter = approx. 1.06 quart. Can I just divide 2000 by 4?

I wouldn't.

2000 L x (1.06 qts/1 L) x (1 gallon/4 qts) = ??

To convert liters to gallons, you need to know the conversion factor between the two units. The conversion factor for liters to gallons is 1 liter = 0.264172 gallons.

Now, let's convert 2000 liters to gallons:

2000 liters * 0.264172 gallons/liter = 528.344 gallons

Therefore, 2000 liters is approximately equal to 528.344 gallons.
