3 in = .25 ft 220 sq ft x .25 = 55 cubic ft 27 cubic ft = 1 cubic yd 55/27 = 2 cubic yds.

Not sure what 2b is but crushed concrete with 1 1/2" rock will cover about 60 square feet. 15 tons ends up being around 12 cubic yards.
39.1116 cubic yards
It depends on how thick the mulch is applied. For example, if applied at an average depth of two inches, the cubic yard of mulch will cover 162 square feet. If applied at an average depth of four inches, half that area or 81 square feet, etc.

1 cubic yard covers 324 square feet per inch of thickness, divide 324 by thickness in inches to get coverage, i.e. 4 inches thick would cover 324/4=81 square feet, 36 inches thick would cover (you guessed it) 9 square feet.
1 (cubic yard) = 46 656 cubic inchesIf the depth is 2 inches then the area it will cover is 46656/2 square inches = 23,328 square inches. Convert 23,328 square inches to square yards23 328 (square inches) = 18 square yards
A cubic yard is 46,656 cubic inches. Spread to a thicknes of 5 inches, a cubic yard of concrete covers 9332.1 square inches, which is 64.8 square feet.
One "yard" of dirt (meaning one cubic yard) contains 46,656 cubic inches. Spread 8 inches thick this will cover 5832 square inches or 40.5 square feet.
"4 inches" is a length. "7676 square feet" is an area. "4 inches by 7676 square feet" describes a volume, which is equal to 2,558.67 cubic feet. (= 7676/3, because 4 in = 1/3 ft.) So your question is better put as "How many tons of crushed stone does it take to cover an area of 7676 square feet to a depth of 4 inches?" The answer depends on the density of the crushed stone. I can't answer that, but I've given your question a clearer phrasing.

1 cubic yard equals 27 cubic feet. At a six inch depth 1 cubic foot will cover 2 square feet, so 27 cubic feet will cover 54 square feet.
The question as stated makes no sense, as square feet is a measure of area and "yard", is a measurement of volume. Normally, "yard" is a measurement of length. However, concrete, soil, gravel, sand, etc., are normally sold (in the U.S.) by the "yard" which is simply short for "cubic yard." However, you may easily calculate the area that a yard of crushed rock will cover, depending on the desired depth of crushed rock. As a cubic yard is 3 feet by 3 feet by 3 feet, which is equivalent to 9 square feet by 36 inches, simply divide 36 inches by the desired depth in inches, and multiply it by 9 square feet. Thus, if you wanted a depth of 8 inches, 36 divided by 8 is 4.5. So, you can cover 4.5 square yards, or 4.5 times 9 square feet = 40.5 square feet, which would be a square area approximately 6 feet 4 inches by 6 feet 4 inches.
1 cubic yard will cover 15 square yards at 3 inches deep.
200 cubic feet or 7.4 cubic yards
1 cubic yard of crushed rock fills 3/depth in feet square yards.
800 square feet x 1/12 x 3/4 = 50 cubic feet.
1 cubic yard/(1/9 of a yard) = 9 square yards.
