I'm setting up a spread sheet for bill of materials. Let's say I have
3x3x1/4 material at 1' 10 3/8" each and 3x3x1/4 at 5' 4 1/8" each. I want
Excel to calculate total in feet and inches. Bascially variable sizes.

I am not sure how to write this so that I can use it for other materials. I
need to find out the total of the material to order. Is there any easy way to
do this?
