The 'square feet' of area that it covers is 1,620/(depth of the mulch, in inches)
For a 12' x 10' area you would need 13.33 square yards of carpet. 12 x 10 = 120 / 9 = 13.33 sy
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.
About 3 1/2 ". 432 x .375 = 162cf / 27 = 6 cu yards
This area requires 2.5 cubic yards.
18ft is equal to 6 yards so a square of 6yds x 6yds would have an area of 36 square yards.
The area of rectangle is : 432.0
If the diameter is 18 ft then the radius is 9 ft = 3 yards. Then the area is pi*r2 = 28.27 sq yards.
The 'square feet' of area that it covers is 1,620/(depth of the mulch, in inches)
That's 13 cubic yards of mulch for every 2 inches deep.
One cubic yard of mulch will cover approximately 160 square feet at 2" deep, so you would need approximately two cubic yards of mulch to cover 271 square feet at 2" deep.
About a 1,944 square foot area at 2" depth of mulch. Roughly equivalent to 12 parking spaces.
Multiply width by length to get the area. The answer would be 342.2 square feet.
1 yard of mulch at 12 inches deep would cover 25 sq. ft., so for 400 square feet you would need 16 yards. 12 inches is the depth you need to start with because the mulch will settle.
It depends on how thick you want to apply it.
Either your structure has five dimensions, or else it's a bin that's 18-ft squareand 4-ft high. We'll assume the latter.Volume = (18-ft x 18-ft x 4-ft) = 1,296 cubic feet = 48 cubic yards
To find the total square footage of an 18ft by 18ft area, you would multiply the length (18ft) by the width (18ft) because the area of a rectangle is calculated by multiplying its length by its width. So, yes, you would multiply 18 by 18 to get the answer. This would give you a total of 324 square feet for an area that is 18ft by 18ft.
