Estimating Cubic Yards


Formula: (square foot area x depth) / 27

This formula should be used for any bulk material, i.e. mulch, loam, crushed stone, etc.

Measure square foot area (width x length)

Choose the desired depth of material (convert inches to feet)

1" = .08 ft2" = .16 ft3" = .25 ft4" = .33 ft5" = .42 ft6" = .50 ft7" = .58 ft8" = .67 ft9" = .75 ft

Square Feet Area x Depth (in feet) = Cubic Feet (width x length x depth)

Divide Cubic Feet by 27 to get Cubic Yards

Example:

To mulch an area of 25 feet wide by 50 feet long at 3" thick:

25 ft x 50 ft = 1250 Square Feet

3 " thick = .25 feet

1250 sq ft x .25 ft = 312.5 Cubic Feet

312.5 Cubic Feet / 27 = 11.57 yards of mulch
