There are 210 inches in 5 yards a 2.5 feet: There are 3 feet in a yard, so 2.5 feet equals 5/6 of a yard. There are 5 and 5/6 yards total. There are 36 inches in a yard: (5+5/6)*36 = 210

Sureley you jest: 1/3 of a yard equals 1 foot, because three feet equals one yard. (Therefore 5 yards equals 15 feet + 1/3rd of a yard which equals 1 foot will equal 16 feet because 15 feet plus one foot equals 16 feet,)
