To test 2 boys at their math skills, a teacher tells them that he can finish 1 side of a rubiks cube in 1 minute, and that the time needed for each additional side will not change (1 min for first side, one min for second side, and so on.)The teacher asks each of the students to tell him how long it will take to finish. Both boys know that a rubiks cube has 6 sides. They both scoff at how easy it is and tell the teacher their answer but get it wrong. What is the correct answer?
U don't scoff.

5 minutes - once the fifth side is finished, the sixth side must be because all the color cubes are used up amongst their correct sides.
