This is a (slightly silly) version of Penguino's [Ernie gift-wrapping puzzle](https://puzzling.stackexchange.com/questions/6346/ernie-and-the-alchemists-gift).

You need to wrap a cubical present with side length 1 meter. As in the linked question, when you wrap a present, you are not allowed to cut the wrapping paper. You can only fold it to cover the cube.

Unfortunately, unlike in the linked question, here you have no triangle. You can only use one rectangle of wrapping paper. The rectangle can have whatever dimensions you like. You want to use the least paper possible. How small can you make the area of the rectangle?
