A friend of mine is looking to start her own business and she would like some help from us. She has developed a recipe for a great mouth-watering chocolate fudge. The pieces of fudge will be sold in centimetre size cubes.

She has bought cardboard material to make the boxes to distribute and sell the fudge, but would like some help to work out some different ways of packaging the units.

If her sheets of cardboard are 20cm by 10 cm, and her cutting machine will only cut squares from the corners, how much could each of the boxes hold?
