Well, lets see.. that's 84 cm equals 33 inches, and 16 cm equal 6.3 inches, so 7 times 6.3 inches equals 44.1 inches around. So 44.1 inches around . wait... the two ends touch top and bottom, so that makes the string 33 inches plus 44.17 inches.. for a total of 77.17 inches. or about 196 cm.
196 cm
