  • Duration: 04:26
  • How does calculating surface area help to wrap presents? Presenter Carol Vorderman reckons we use enough Christmas wrapping paper to wrap up Guernsey, but how good are we at wrapping those presents? We can mentally visualise the surface area of a box and so make a good guess at how much paper we will need, but mathematician Sara Santos has devised a formula allowing perfect wrapping every time without wasting paper.
