Final answer:
To completely empty a 5-gallon bucket of cooking oil, you would need 19 one-liter containers.
Step-by-step explanation:
To calculate the number of one-liter containers needed to empty a 5-gallon bucket of cooking oil, we need to convert the gallons to liters. There are approximately 3.785 liters in a gallon. So, to convert 5 gallons to liters, we multiply by 3.785:
5 gallons * 3.785 liters/gallon = 18.925 liters
Since each one-liter container can hold 1 liter of oil, we divide the total liters by 1:
18.925 liters / 1 liter/container = 18.925 containers
Since we cannot have a fraction of a container, we round up to the nearest whole number. Therefore, we would need 19 one-liter containers to completely empty the 5-gallon bucket of cooking oil.
