This is a Pythagorean Theorem problem. a^2= b^2 + c^2 (a = hypotenuse length). 4^2 = 3^2 + x^2 16 = 9 + x^2 x = sqr(25) = 5 inches !!!!

Question:

John has 84 Lego pieces. He fills 5 boxes with exactly the same amount of Legos in each. How many cards did he put in each box and how many did he have left over?

This sounds like a division problem. We want to do is divide the total amount of Lego pieces by the number of boxes. 64 divided by 5 is 12 with 4 remaining. This means he must have put 12 Lego pieces in each box and was left with 4 remaining pieces.
