40.1 cubic yards
280 / 9 square yards x 2 / 36 yards = 1.7284 cubic yards (about 1 3/4 cu yds)
123.44 cubic yards
How thick? Gotta have thickness to calculate cubic yards.
For 576 square feet at a depth of 4 inches, you will need 7.11 cubic yards.
multiply the number of square yards - which is an area - by the average height in yards to get the volume in cubic yards
For a 4-inch depth you will need 7.41 cubic yards.
You cannot "fill" a cubic measurement with a square measurement.I think you meant cubic yards.1 cubic yard = 27 cubic feet.Your concrete slab is 1600 x 4/12 cubic feet = 533.333333... cubic feet.533.333333... cubic feet / 27 = 19.753 cubic yards (rounded to third decimal).
You can't convert cubic measure to square measure.
This is not a valid conversion because cubic yards is a measure of volume while square yards is a measure of area.
The term "yards" of concrete means cubic yards.
That makes no sense. -Square yards is AREA. -Cubic yards is VOLUME . They are totally different. (However, 3 yards cubed, i.e. 3 yards x 3 yards x 3 yards = 27 CUBIC yards)
