A room has dimensions 4.30 m x 4.30 m x 4.30 m. On day one, a butterfly starting at one corner flies straight, ending up at the diagonally opposite corner. On day two, the butterfly walks rather than flies, taking the shortest path, starting at one corner and ending up at the diagonally opposite corner.  What is the difference in length (in feet) traveled by the butterfly during those two days? (Use: 1 m =3.281 ft)
