Coverage Formula for Bulk Materials

1 c.y. is 3’ x 3’ x 3’ (2 skid loader buckets full or 9 wheelbarrows)

1 c.y. covers:

  • 325 s.f. @ 1” deep
  • 162 s.f. @ 2” deep
  • 108 s.f. @ 3” deep
  • 81 s.f. @ 4” deep
  • 54 s.f. @ 6” deep

To figure yards of bulk materials:

Length x Width x Depth in inches divided by 324 = c.y. needed

(12’ x 12’ x 3” = 432 ÷ 324 = 1.33 c.y.)

 

Pickups:

  • Small truck general holds 1 skidloader bucket of mulch
  • Full size with small box holds 1 ½ - 2 buckets of mulch
  • Full size with full bed holds 4-5 buckets of mulch
