I am trying to calculate minimum and maximum quantity price per items for a tender offer. My problem is there are different metrics in my Excel sheet. It is easy to calculate prices per items because they are simply quantities. However, when it comes to cubic meters, I do not know where to begin. For instance, what is one item/unit price for 1.3 tonnes. If I divide 5,000 dollars to 1.3, the result is 3.846 . Seemingly this is not what is desired as a unit price. Any help would be appreciated.
