What is the formula for working out the volume of a suitcase and why is this always given in litres?

It depends on the shape of your suitcase!!! If it is a standard rectangular shapr then just multiply the lenght by the breadth by the height. I have never seen a size in litres - answer should based on the measurements used. Can only think that some bright spark thought it was easier to compare sizes - divide by 4.5 to get a rough equivalent in gallons. -------------------------------------------------------------------------------- 'The wages of sin is death' (Romans 6:23) BUT THE HOURS ARE GREAT!!

As Fatchance said multiply the height by the breadth by the depth. Measuring the internal dimensions in centimetres and dividing the answer by 1000 will give the capacity in litres. For other than rectangular shapes either advanced maths or a practical method will be required. Litres are used because they are the international unit of volume used in all major countries, with the exception of the USA. Mar 29 02, 11:15 AM

A litre is (for all practical purposes) a cubic decimetre. If you need to convert litres into Anglo-Saxon measures, a litre is just over 61 cubic inches, and there are about 28.3 litres to a cubic foot. Mar 29 02, 12:55 PM
