a packaging company manufactures a cardboard box with a volume of 864 cubic inches. the length of the box is 24 inches, and the ends of the box are square. what is the height of the box in inches?

volume = length x weight x height
the ends of the box are square, so
height = weight
volume = length x height x height
plug in the numbers and solve for height 
I think on the first and fourth line, Cat meant width vice weight.
