No, it sure doesn't sound right to me.

450 sq. ft @ 2'' coverage = about 3 yards

450 sq. ft @ 3'' coverage = about 4 yards

Try using this formula :Length times Width times Depth.Then divide that by 324

450 sqft times 3 in deep=1,350
1,350 divided by 324=4.166 yards of mulch

what is the 324?and how what is it ?

thanks

2" depth 3yards
3" depth 5yards
4" depth 6 yards
All were rounded of to the highest nuber on the mulch calculator we use.

Im not sure, that is the formula I was taught with and thats what I have been using for the last 2 years myself.Never no problem with shortage or overage. We have been putting down 40-75 yards of mulch a week for the last month or more,and no problems.Happy Bidding

12 x 27 = 324

12 inches in a foot, 27 cu feet per cubic yard

Length (ft) x width (ft) x depth (inches)/ 12 = cu ft required

cu ft required / 27 = cu yards required

OR

Length (ft) x Width (ft) x depth (inches) / 324 = cu yards required

Mikey,
Here is the formula for figuring yds.....
This is the true mathematical way to figure it....

ok..i will break it down for you...

if you have an area that is 450 sq.ft. and you want to cover that area with 3" of mulch....then this is how u do it

measured area (450 sq ft) X how deep you want the mulch (3" or rather .25') = 112.5 sq ft.

Now to get it to yard do this......... 112.5 / a cubic yard (27)= 4.166 yards

That is the scientific method of figuring yards.....out of a square ft..area....

Hope this helps....if you need anything else.....feel free to email me.....

Life is short, Have fun

OOPS.... sorry to nit pick but that should be 112.5 cubic feet. Lenth x width x depth = volume (in cubic units)
