Formulas to help you get what you need.


 

Here are some simple formulations to calculate how much product you will need. Or if you prefer, simply contact us and we will be happy to assist you.

Squares & Rectangles

Area (Square Feet): Length x Width = Square Feet (sq.ft.)
(Example:  6' long x 4' wide = 24 sq.ft.)

Depth (in feet): Inches Deep ÷ 12 = Depth (in feet)
(Example: 3 inches ÷ 12 = .25 feet)

Cubic Feet: Area x Depth(in feet) = Cubic Feet (cu.ft.)
(Example: 24 sq.ft. x .25 feet = 6 cu.ft.)

Tons Needed:  Cubic Feet ÷ 20 = Tons
(Example: 6 cu.ft. ÷ 20 = .3 Tons)

Yards Needed: Cubic Feet  ÷ 27= Yards
(Example: 6 cu.ft. ÷ 27 = .22 Cu. Yds. (Cubic Yards) 

 

Circles

Area (Square Feet): Diameter x .7854 = Square Feet (sq. ft.)
(Example: 12' across  x .7854 = 113.1 sq.ft.)

Circumference: Diameter x 3.1416. = Linear Feet Around
(Example: 12' across x 3.1416 = 37.7 Linear Feet Around
**Note: Circumference is the running feet around the border of a circle.

Depth (in feet): Inches Deep ÷ 12 = Depth (in feet)
(Example: 3 inches ÷ 12 = .25 feet)

Cubic Feet: Area x Depth(in feet) = Cubic Feet (cu.ft.)
(Example: 24 sq.ft. x .25 feet = 6 cu.ft.)

Tons Needed:  Cubic Feet ÷ 20 = Tons
(Example: 6 cu.ft. ÷ 20 = .3 Tons)

Yards Needed: Cubic Feet  ÷ 27= Yards
(Example: 6 cu.ft. ÷ 27 = .22 Cu. Yds. (Cubic Yards) 

Tidbits

  • A ton of most loose stone products cover 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.
