- ONE (1) Yard of COMPACTED Aggregate will cover approximately: 1" thick = 200 sq. ft. 2" thick = 100 sq. ft. 3" thick = 75 sq. ft. 4" thick = 50 sq. ft. 5" thick = 38 sq. ft. 6" thick = 25 sq. ft. 12" thick = 15 sq. ft.
- To Calculate # of Yards: length (in feet) x width (in feet) x depth (in inches) divided by 12 divided by 27
- Natural Stone calculate approximate # of tonnes: length (in feet) x width (in feet) x height (in inches) divided by 12 x 170 divided by 2000
