landscaping question

I used a sod cutter that was set at 1.5 inches so i don't know. Its not purely sod, lots of weed, thats why I'm replacing it
 
1200 sq ft X .125(1.5/12) =150 cubic feet / 27 = 5.5 cubic yards.

You will probably have a bunch less than that but you might want to call
416-674-0022 for a small bin. ( Classic Disposal Toronto)

Good luck
