Answer 1

A killogram is 2.2 pounds

4 kilograms = 8.8 pounds

a gallon of water weighs 8.35 pounds

181 pennies made after 1983 weigh a pound

Just keep on putting pennies in a small shoe box until you get 8.8 pounds

Answer 2

1 litre of water = 1Kg

so 8 bottles of 500ml   water  is roughly 4kg

Answer 3

4 bags of sugar or 4 litres of water.

The metric weight system is based on water.

1000ml is a litre and each ml of water weighs a gram so a litre of water weighs 1 kilo. Therefore 4 litres of water weighs 4 kilos.

Also 1 ml is 1 cubic centimeter.
