Cad queen 2000 your math is on the right track. I made my quilt out of 60 strips which technically means it was 2400 quilt LOL. I wanted it bigger and no borders. I did the math, said a little prayer, got entangled in 2400" of strips and in couple if hours my quilt top was done. I snipped off a chunk of fabric from the first strip and I don't think I measured it. If I did I do not remember. My strips did not go well together at all but the quilt turned out quite nice. Good luck!
