THE CARDBOARD BOX

This puzzle is not difficult, but it will be found entertaining to discover the simple rule for its solution. I have a rectangular cardboard box. The top has an area of `120` square inches, the side `96` square inches, and the end `80` square inches. What are the exact dimensions of the box?
