IT’S (almost) CHRISTMAAAS! Yes that’s right, in approximately 150 hours it will be Christmas Day. This means next Wednesday morning, there will be people of all ages around the country tearing open around 230,000 miles of wrapping paper to discover what presents await inside. And that’s just Britain.
I’ve always wondered the point of wrapping presents neatly and efficiently, just for the paper to be torn apart in sheer excitement but I guess there’s an art of wrapping presents gracefully. A few years back I remember hearing in the news the discovery of a ‘formula to wrap presents’ and having conducted some research, I’m glad to find this memory was real (you can never be too sure). There were two different formulae I found; one involved efficient wrapping and the other ‘perfect’ wrapping.
In relation to my earlier statistic, it is perhaps more relevant to discuss the best way to wrap a present and avoid wasting paper – to reduce both costs and our waste footprint. The following formula works for a cuboid (and thus cube) shaped present and ensures enough paper is cut to make the folds of the wrap too:
A1 = 2(ab+ac+bc+c²)
where A1 = area needed; a, b, c = dimensions of the cuboid where a is the longest and c the shortest.
You can find more info about this here, as well as see how to wrap a cylindrical present or bottle:
Oh and by the way, this formula was created by a former member of the Department of Mathematics at the University of Leicester – Dr Warwick Dumas – yay. Have fun wrapping and don’t forget the cute little ribbon on top!
Merry Christmas! 🙂
