george can make a square using 4 pipe cleaners.how many pipe cleaners does he need to make 3 squares and why?

if george had a package of 200 pipe cleaners,how many would he have left over when he finished making his 3 squares?

If he made three different squares he would need 3*4= 12 but if he can put them beside each other sharing sides he only needs 4+3+3 = 10

So he'd have 190 pipe cleaners left.
