L = length / = per
W = width CY = cubic yard
SQ = square feet or foot x = times
FT = feet or foot ' - feet or foot
" - inches Circumference of Circle = around the outside
LBS = pounds Diameter of Circle = across the whole circle
T = tons Radius of Circle = across half of circle
Ground Cover = River rock or Crushed Decorative Rock
Ground cover: The very first step to your project is to measure the area you want to cover. MEASURE - DO NOT GUESS. We know you may have some odd shaped areas, measure the best that you can.
Area of a rectangle or square - L in ft x W in ft = Sq ft
Area of a right triangle - L in ft x W in ft divided by 2.
Area of a Circle = (radius x radius) x 3.14 = Sq ft
Figure circumference of a circle using radius = radius x 2 = diameter x 3.14 = circumference
Figure radius of a circle using circumference = 3.14 x 2 = 6.28 then take circumference divided by 6.28 = radius in feet
Area of an Oval - (1/2 of L) x (1/2 of W) x 3.14
1 y (not cubic)= 3' (36")
1 cy is a 3' x 3' x 3' cube or 27 c ft.
A sq y - 3' x 3' = 9 sq ft
Inches x inches divided by 144" = sq ft.
Circular hole in ground - Volume = (radius x radius) x 3.14 = sq. ft. Then take sq. ft. x depth in feet = c. f. divide by 27 c.f. = c.y.
Heavy weight bulk groundcover from a 1/2" - 2" size - 1 t = 100 sq ft 2" deep
Heavy weight bulk groundcover that is a straight 2" size - 1 t = 75 sq ft 3" deep
Lite weight bulk groundcover - 1 t = 220 sq ft 2" deep
Sand or limestone screenings (loose material not compacted) - ratio is approximately .84 ton / 100 sq ft 2" deep. Tonnage take c.f. divided by 27 cf = yards x 1.4 for sand & screenings or 1.5 for crusher run limestone.If you have measured in cubic feet or cubic yards use the above formula at the appropriate points.
Mulch - 1 cy = 150 sq ft 2" deep. For comparison, if there is 2 cubic feet in a bag of mulch. A cubic yard is 27 cubic feet. So it would take 13 1/2 bags to make a cubic yard.
Dirt - 1 cy = 125 sq ft 2" deep non-compacted. There is a 30% loss of volume when you compact. A cubic yard is approximately 1.3 ton depending on moisture content.
Flagstone - coverage depends on thicknesses and gapping most will cover - 1 t = 100 - 150 sq ft with an approximate 1 " gap. The thinner it is the more it covers. Some thicknesses are then not appropriate for walking on unless appropriately set in concrete.
Boulders - we suggest measuring the area that you want to put it in including height that you want. Boulders usually look bigger when you get them home than what they look like in our yard.
Boulder size versus weight. If the boulder was a perfect square cube (which we know it is not), a .95' x .95' boulder weighs approximately 75 lbs. a boulder that is 1.30' x 1.30' weighs approximately 200 lbs. So what we tell you as the customer is that a generous size basketball weighs about 100 lbs. Volcanic boulders that are the same sizes are about half of the weight.
A cy of dirt or mulch is 1 scoop on our skidloader.
On rock there is a little over 1 1/2 ton in a cubic yard, so a cy of rock is 2 scoops on our skidloader.
1 skidloader bucket is about 3/4 ton of rock.
