2700 x 4/12 = 900 cu ft 27 cu ft = 1 cu yard 900/27 = 33.33 cu yds
2100 x 1/12= 175 cu ft 175 cu ft/27 cu ft per yard = 6.5 cu yds
sq feet to sq yards cu ft to cu yards you need depth added to your sq ft to get cu ft such as 70 sq ft x 4 in deep = 23.33 cu ft =.086 cu yd
9 Sq ft = 1 Sq yard 4113 Sq ft = 457 Sq yard.
1 yard = 3 ft so 1 sq yard = 3 ft * 3 ft = 9 sq ft Then 4356 sq ft = 4356/9 = 484 sq yard
25' x 4' = 100 sq ft. 100 sq ft x 1' = 100 cu ft. 100 cu ft x 2 = 200 cu ft.
1 sq yard = 1 yard * 1 yard = 3 ft * 3 ft = 9 sq feet So 2.5 sq yards = 2.5*9 sq ft = 22.5 sq ft.
The height (or depth) is missing.
1000 sq ft x 2 ft = 2000 cu ft / 27 (cubic feet in a yard 3 x 3 x 3) = 74.07 yards 1000 sq ft 2 in (2" /12" = 0.1666 ft) = 166.66 cu ft / 27 = 6.172 yards
9 square feet in one square yard.WORK:1 yard = 3 ft, 1 yard X 1 yard = 1 sq yard, Substitute: 3 ft X 3 ft = 9 sq ft
NOT sq ft 1yd concrete is 27 cubic ft
I presume 1 yard of mulch means 1 cu yard of mulch 1yd = 3ft 1 cu yard = 1yd x 1yd x 1yd = 3ft x 3ft x 3ft = 27 cu ft. 12 in = 1ft 1in = 1/12 ft 3in = 3/12 ft = 1/4 ft volume = area x depth => area = volume / depth = 27 cu ft / (1/4 ft) = 108 sq ft.
