How many devices fit in a sq foot? 
20071121 

From JB: We buy product in rolls: 54" x 150'. We make a product that is 2 x 3.5 inches out of this roll and sell by the each. How do we convert this? What is the formula to determine how many devices fit in a sq foot. Then we / by 12? PLEASE help. Thank You. Answered by Victoria West.
