A rectanguler piece of metal is 5 inches longer than it is wide. Square with sides 1 inches longer are cut from the four corners and the flaps are folded upward to form an open box. If the volume of the box is 644 inches, what are the original dimensions of the piece of metal?

5+5+7+21...
original dimensions: x and x+5

(x-2)(x+5-2)(1) = 644

Now just solve for x.
