120' inch round table cloth needs how many yards of fabric to make it?

To determine the amount of fabric needed for a round tablecloth, you can use the formula: fabric length = diameter of the tablecloth + desired drop + desired drop + 20 inches for hems and seams. In this case, the diameter of the tablecloth is 120 inches, so the fabric length would be 120 + 20 + 20 + 20 = 180 inches. To convert this to yards, you would divide by 36 (since there are 36 inches in a yard), resulting in 5 yards of fabric needed.
