EXAMPLE:
How many yards to cover an area 21 feet long and 15 feet wide to be covered 4
inches deep with mulch? Step
One: (determine sq. feet)
21 feet long x 15 feet wide = 315 square feet Step
Two: (determine cubic feet)
315 square feet x .33 (chart number for 4 inches deep) = 103.95 cubic feet Step
Three: (determine cubic yards)
103.95 cubic feet divided by 27 = 3.85 cubic yards (round up to 4 cubic yards) |
