Look on this piece this is what I see
7" X 1" if your plating both sides that is roughly 14 sq I meen I can see there are holes on the ends but you don’t tell the thickness of the piece there is room for error its not an exact science
its kinda like a Volkswagen engine if you over think it you will Jack it up try and think simple
I hope this helps also you can try the surface area calculator on Caswells web site
