Thanks for Reading, Everyone.
Hopefully my attachment will help clarify.
My problem: Imagine a semi-trailer truck in this instance. I need to know the total combined weight of the freight for each individual compartment. The trailer is divided up into bins C at the very front through J at the rear. These bins (C -> J) are different lengths, as are the freight bundles/boxes when they arrive. So the boxes are loaded as they arrive from front to rear with no space inbetween. The bins are not physically divided so boxes from one compartment will overhang into the next.
Example: Box 1 is long enough to fill up bin C,D, & 1/2 of E. Box 2 is short so it only fills up to the 3/4 mark of E. Box 3 fills up the rest of E and fills 1/3 of F. I'd like to plan for at least 20 boxes and give the loader the option of where to start loading the freight (If there are only two boxes he/she would probably start loading them in bins F.)
I figured I would need to first find each freight bundle's weight per inch... but have now realized this gets real complicated fast. I'm in over my head.
Best Thanks to anybody who can help,
David
