I have raw materials costs
3% loss of raw materials, because of packaging requirements
Packing materials costs
2% damaged materials
Manufacturing expense
Truck delivery fee
Storage fee
Wages p/year
Manufacturing costs p/yr.

Please help!!

Not sure what you mean by unit?

If you are looking for cost by the ounce?

12 pack is 144 ounces.

2 liter is 67.6 ounces.

I'm a little confused by your question, hope this helps.
