Trying to decide how much soil you’ll need to redo the flowerbed or how much sand it will take to fill up the hole from the old swimming hole. Below are some formulas to help out. If you have any trouble, give our office a call and one of our customer service representatives will be happy to figure the area(s) for you.
Squares & Rectangles
- Area: Length X Width. Example: Length = 6′, Width = 4′. 6′ x 4′ = 24 sq.ft.
- Depth: Inches Deep/12 = Decimal Depth. Example: Depth = 3″/12 = .25
- Cubic Feet: Area X Decimal Depth = Cu. Ft. Example: 24 sq.ft. x .25 = 6 cu.ft.
- Tons Needed: Weight per Cubic Foot X Cubic Feet needed. Example: Product =100 lbs. per cubic foot. 6 cubic feet needed.
- 100 x 6 = 600 lbs./2000 = .3 Tons
- Yards Needed: Cubic Feet/27. Example: 6 cu.ft./27 = .22 cu.yds. or ¼ cu.yd.
- Area: Diameter X .7854 = sq.ft. Example: Diameter =12′ x 12′ x .7854 = 113.1 sq.ft.
- Circumference: Diameter X 3.1416. Example: Diameter = 12′ x 3.1416 = 37.7 Linear Feet. Note: Circumference is the running feet around the border of a circle.
- A ton of most loose stone products covers roughly 80 sq.ft., 3″ deep.
- A yard always covers 108 sq.ft., 3″ deep.
- Always figure compaction for areas over 6″ deep. Compaction for sand and soil is about 15 to 20%. On most products a ton is equal to 75% of a cubic yard.
- For any other shapes you can fax, e-mail, or mail a rough drawing to our office.
