4 1/3 squared is .. about 19 square yards
13 X 16 divided by 9 = 23.11 square yards
6 sq. yds
20 feet x 20 ft x .3333 ft = 133.33 cubic feet / 27 cubic feet per yard = 4.94 cubic yards
(22/3 square yards) divided by (depth of mulch in inches)
10-ft x 15-ft = 150 square feet = (16 and 2/3) square yards
18 ft * 18 ft * 2 inches = 6 yards * 6 yards * 2/36 yards = 2 cubic yards.
500 sq ft X 1/12 ft / 27 cubic ft./cubic yard = 1.5 cubic yards
16553 sq ft * 2 inches = 16553/9 sq yards * 2/36 yards = 16553*2/(9*36) cubic yards = 102.18 cu yards.
80 yards is a measure of distance, not of area so the answer depends on the shape of the cases.
