To find the price of a square inch out of a 2 foot by 30 foot roll of vinyl at the cost of 30?
A roll 2 foot by 30 foot contains 60 square feet. There are 144 square inches in a square foot. So the roll contains 8630 square inches = and you get all of these for 30 units of currency. I will assume that the unit of currency contains 100 smaller units. so the price is 3000 small units. This means that the cost per sq inch = 3000/8630 = 0.347 small units = just slightly more than one-third of the small unit.
