(22/3 square yards) divided by (depth of mulch in inches)
The 'square feet' of area that it covers is 1,620/(depth of the mulch, in inches)
15 square yards at 3 inches deep.
how to get 1600 mulch which is money in bin weevils
1 cubic yard will cover 15 square yards at 3 inches deep.
Just over 10 yards. (10.2)
To solve this convert all measurement to a yard or square yard basis: 3 inches is 0.083333333333 yard and 1500 square feet = 1500/9 = 166.6666666666667 square yards Thus the amount of mulch you need is 166.6666666666667*0.083333333333= 13.88888888883333 cubic yards. so you need to purchase 14 cubic yards of mulch for the job.
33.33 cu yds
That's 13 cubic yards of mulch for every 2 inches deep.
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.
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.
