    This week’s question

You have to order wrapping paper for presents. Given the length, width, and height of the boxes you need to wrap, return the number of square feet (or whatever units you want) of wrapping paper you need to order. Extra credit: allow for other shapes of presents and their dimensions!
Example:
$ wrap(2, 3, 4)
52 square feet

My answer
Take the area of all sides:
function wrap(length, width, height) {
  const area = 2 * (length*width + length*height + width*height);
  return `${area} square feet`;
}
But arguably, when you wrap a present, you usually need more than the exact area—just so you can get nice folds and stuff.
So I'd say you'd have to at least do 1.25x (if not 1.5x) that amount...
