Okay, I installed a bunch of mulch yesterday. I went to supplier, and had 8 yards of mulch dumped into my 1 ton dump Went to customer site and using a 6 cf wheelbarrow, made 43 trips with mulch. So.... 6cf * 43 = 258cf 258/27 = 9.5yards Plus I still have a strong yard or so left in the truck. Do I need to figure compaction or anything else into my wheelbarrow numbers, or did I really do 9.5 yards of mulch??? I'm doing the invoice and just want to make sure I'm charging the customer appropriately. Now, I have 6 1/2 foot sides on the one ton right now, so it will hold that much. Plus, the mulch was loaded with a 20 yard bucket, so not real exact measurements when I was loaded.
