Explanation

The value of liquid gallon is defined as 231 cubic inches and equates to approximately 3.785 litres.

1 litres = 0.22 gallons = 1000 cm3.

One imperial gallon is equivalent to approximately 1.2 U.S. liquid gallons.

1 imperial gallon = 4.546 litres

Explanation

Source reduction is the most preferred method in the waste management hierarchy because it prevents waste generation at the source, avoiding the need for disposal or recycling.

It reduces resource consumption, pollution, and costs associated with waste handling, making it the most sustainable approach.
