Area of Metal for Decoiled Straight on Report Not Accurate

[msheofsky]

I'm trying to run a report for the total area (Sq. Ft) of metal for decoiled straight on our coil line.  For instance, I have (2) pcs of 20x8-56" lng ductwork. The report will show the blank size (2@60x29.750) which is correct.  But all the reports will give me an area of 49.301 for this instead of the actual 49.5833.  How can I get this to match up for charging out correct material amounts to projects?

From your report, if you have the following items listed below, or you can add them, then use a CALC field and in it have it calculate the following

(Development Width* Development Height * Item Blank Qty )/ 144

See if this solves your riddle
