Mulch is often sold by weight in bags, but a volume is assigned to the material in bags, too. We'll treat this as a volume problem as we have an area to cover (880 square feet), and a depth of coverage assigned (2 inches). We have to find the volume of that 880 square feet by 2 inch volume. First, we need to convert either the area in square feet to square inches, or the depth in inches to feet. The latter makes more sense (and it's easier), so let's do that.The 2 inches is 2/12ths of a foot, or 1/6th of a foot. We'll go with that. If we have 880 square feet by 1/6th of a foot in depth, we have 880 square feet times 1/6 feet, which is 146 2/3rds cubic feet of mulch, the required amount of mulch to cover the given area to the desired depth.

About a 1,944 square foot area at 2" depth of mulch. Roughly equivalent to 12 parking spaces.

3 inches = 1/4 footVolume = (308 x 1/4) = 77 cubic feet.That's (77/2) = 38.5 bags

The area of a circle is the product of the square of the radius squared and the number pi. The area of a semicircle is half the area of the corresponding circle. The diameter is twice the radius. Therefore, the area of this semicircle is pi(15/2)2/2 = 8 X 101 square feet, to the justified number of significant digits -- only one, since the value 6 has only one. At 6 square feet of mulch per bag, over 13 bags of mulch will be needed; therefore, 14 bags should be available.

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.

The 'square feet' of area that it covers is 1,620/(depth of the mulch, in inches)

15 square yards at 3 inches deep.

For 1 foot deep, 400 cu ft. For 3 inches deep, 100 cu ft.

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.

Half a cubic foot.

That's 13 cubic yards of mulch for every 2 inches deep.

One cubic yard will cover a 324 square-foot area with one inch of mulch. However your mulch should be 2 to 3 inches thick to maintain moisture and prevent weed growth. Be careful not to go to thick or you will cause mold to form in the mulch.
