0. Do you mean 70 cubic feet? 1 sq yd = 27 cu ft.
133.33 cubic yards, that's 400 feet
You also need to specify the average depth.(And by "yards" we assume you mean cubic yards).
It depends on whether the dimensions given are in feet or yards or metres or some other unit.
None because it's a hole but 6 cubic yards of dirt will fill it up.
About 3 yards with a little left over. 2.78 yards.
You are mixing volume (square yard) and area (length x width). How deep do you want the dirt? One foot deep you need about 80 square yards of dirt.
You can't fill a space with yards, only with cubic yards (27 cu.ft.).28 x 12 x 1/3 = 112 cubic feet / 27 cubic feet = 4.148148...cubic yards will be required.
14 cubic feet = 0.518 cubic yards
12 x 12 x 3 = 432 ft^3 = 144 yds^3
20ft x 10ft x 7ft = 1400 cubic feet 1 yard of dirt = 27 cubic feet Hence yards required = 1400/27 = 51.85
Sorry the first answer was in square yds. Cubic yards would be 0.308639
A yard is 3x3x3 = 27 cubic feet, so 7 yards is 7x27=189 cubic feet
