    I have about 5300 square feet to mulch at about 2 in thick.
    How many yards do you figure, and how do you figure out your numbers.

    multiply lenghth x width x thickness you desire. do this in inches and then divide by 12 3 times and then 27 (27 sqft in a cubic yard)will give you yards So 5300sq ft would be 5300 x 12 x 12 x 2" / 12/12/12 /27 would be a hair less than 33 yards. Then, this is where the experience comes in, subtract for the landscaping. I.e. hedges, bushes, flowers and such.
    Good luck.

    Also I find easy is to multiply length X wdth X 8.3 (for one inch or 16.6 for two inches and so on) then divide by 27 to get your yardage you need. If you are working with matterials that will compact remember to add @18-20% for compaction.

    Here is the quick formula I use. A yard covers 81 sq ft @ 4", 121 1/2 @ 3", 162 @ 2" ,and 324 @ 1". All you have to do if you are putting it down 2" is divide your square feet by 162.

    5300 square feet at 2 inches :

    2inches divided by 12 inches = .1666

    5300sqft x .1666 = 882.98

    882.98 divided by 27(27 sqft in a cubic yard) = 32.70 or 33 yds of mulch needed

    Seems like we all have our own little way at comming out with our special little number. And to think my math teacher 10 years ago said you have to do it the same to get the right answer.

    Seems like a lot of people on this site have skipped their high school math classes. It was a waste of time then, how about now?
