Multiply the two dimensions to get the area. The calculation will give you 720 square inches.
The roll has 12.5 square feet of material.
To find the price of a square inch out of a 2 foot by 30 foot roll of vinyl, first calculate the total area of the roll by multiplying the length and width: 2 feet * 30 feet = 60 square feet. Since there are 144 square inches in a square foot, the total square inches in the roll is 60 square feet * 144 square inches/square foot = 8,640 square inches. Divide the cost of 30 by the total square inches to find the price per square inch: $30 / 8,640 square inches = $0.00347 per square inch.
2 x 10 x 36 = 720 square inches... 720 / 18 = 40 units !
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.
