Locker problem

How many lockers are open? Me and my classmates figured out that there are 31 lockers open. This was very hard to figure out because there are so many ways to get answers to this problem. But once you get at least one equation it is very easy to follow the pattern. This also had to do with figuring out the perfect squares or you wouldn’t be able to figure out the lockers that were open. Which lockers are open? This was the really hard part to figure out in the problem. We all worked together and figured it out. I used square roots to figure out which lockers were open. Which lockers are perfect squares? We came to a conclusion that the perfect squares are (1*1), (2*2),(3*3). So you use perfect squares to figure it out. They have an odd amount of factors they will change there state to opposite (o, c, c ) These lockers were open because the students came through and opened and closed them, so some lockers were never touched again.
