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.

20 sq ft = 20*12*12 = 2880 sq inches 8 inch * 10 inch = 80 sq inches. Maximum number of rectangles (NOT SQUARES!) is 2880/80 = 36. This is a maximum because the answer depends on the dimensions of the roll. If, for example, the roll were 1 ft*20 ft, you will get only 1 rectanle across and 30 along the length. You will have a 2 inch*20 ft strip of waste.
