Fabric weight is usually listed as a GSM value. (Grams per square metre) This is the weight for 1 square metre. (1 metre x 1 metre) If fabric is on a roll, measure width of the roll, and multiply by GSM rating to get weight in grams per linear/lineal metre. Examples - GSM rating 500, Roll width 2.5 metre= 1250g or 1.25Kg per linear metre. GSM rating 155, Roll width 3 metre= 465g 0r 0.65Kg per linear metre.

The roll has 12.5 square feet of material.
Multiply the two dimensions to get the area. The calculation will give you 720 square inches.
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 !

37.5 square feet.
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.

24 inches*50yards = 24 inches * 50*3*12 inches = 24 inches * 1800 inches = 43 200 square inches.
