To calculate how many hours it will take to fill the 10-gallon aquarium, we need to convert the volume measurements to a consistent unit. Since 1 gallon is equal to 4 quarts, the aquarium holds 40 quarts of water. With 1 quart being added every 3 minutes, it would take 120 minutes (or 2 hours) to fill the aquarium.
well 4 quarts is one gallon, and he has 5 gallons to fill. 4 x 5 is 20, so he will have to fill it 20 times.
