How do I calculate the number of bags of mulch I will need to cover the ground in my flower beds?
Question:The measurements are 40 yards by 10 yards.
Answers:
You convert that to feet. Multiply length x width x depth. You get depth by dividing the number of inches deep you want the mulch by 12(# inches in a foot) . This should be a decimal. Then divide by 27 (cu ft in a yd). This answer will be cubic yards. Generally there are 13.5 bags in a yard if they are 2 cu ft bags and 9 in a yard if they are 3 cu ft bags.
EX. 120 X 30 = 3600
3600 x .17 = 612 ( .17 is 2 inches)
612 / 27 = 22.67 or 23 yards
23 x 13.5 = 311 bags if 2 cu ft
OR 23 x 9 = 207 bags if 3 cu ft
You may get off cheaper buying bulk mulch rather than bagged.
it depends on how deep you want it. I just bought bags from Loews and it tells you on the back of the bag how many you need.
It depends on how think you want and how big the bags are.
The bags have directions and will specify the voverage ata set height. You have 400 SQ yards. Key thing to remember is that you have 3600 SQ feet (not 1200). BP
