How to compute the amount of materials needed:

Sold by the cubic yard: soil, mulch, compost, fill dirt.

Sold by the ton: aggregates, sand, ball diamond clay, golf course material.

Inches to Feet

• 1" divided by 12"=.08'
• 2" divided by 12"=.17'
• 3" divided by 12"=.25'
• 4" divided by 12"=.33'
• 5" divided by 12"=.42'
• 6" divided by 12"=.50'
• 7" divided by 12"=.58'
• 8" divided by 12"=.67'
• 9" divided by 12"=.75'
• 10" divided by 12"=.83'
• 11" divided by 12"=.92'
• 12" divided by 12"=1.0'

For materials sold by the cubic yard:

• L x W x D divided by 27 = cubic yards

• Multiply length by width = square feet

• Multiply square feet by depth (inches divided by 12) = cubic feet

• Cubic feet divided by 27 to= cubic yards

For material sold by the ton:

Use the same formula as calculating for cubic yards

Multiply the cubic yards by the tons per cubic yard conversion (table 2)

Area of a circle:

3.14 X the radius (1/2 the diameter of a circle) squared = square feet. You can now take the square feet and convert to cubic yards or tons.

## Conversion Chart on Coverage for Mulches and Compost

1 cubic yard will cover:

• 324 Sq. Ft. = 1" Deep

• 162 Sq. Ft. = 2" Deep

• 108 Sq. Ft. = 3" Deep

• 81 Sq. Ft = 4" Deep

• 65 Sq. Ft. = 5" Deep

• 54 Sq. Ft. = 6" Deep

3.0 cubic ft bags will cover:

• 36 Sq. Ft. = 1" Deep

• 18 Sq. Ft. = 2" Deep

• 12 Sq. Ft. = 3" Deep

• 9 Sq. Ft. = 4" Deep

• 7 Sq. Ft. = 5" Deep

• 6 Sq. Ft. = 6" Deep

## Yard to Ton Conversions

 Topsoil 1 yard = 1.0 ton Mulch 1 yard = .5 ton Mixed Soils 1 yard = 1.0 ton Compost 1 yard = 1.0 ton Silica Sand 1 yard = 1.3 ton Slag 1 yard = 1.1 ton Gravel 1 yard = 1.4 ton Decorative Stone 1 yard = 1.3 ton Recycled Concrete 1 yard = 1.3 ton Brick Materials 1 yard = 1.3 ton Ball Diamond Clay 1 yard = 1.5 ton Limestone 1 yard = 1.4 ton

## To convert yards squared yards to yards cubes, divide by 9 To convert cubic feet to cubic yards, divide by 27

## How much mulch do I need?

How to read the table:

• Figure the length of the area to cover.
• Figure the width of the area to cover.
• Multiply length by width to calculate the square footage.
• Locate the square footage on the chart on the next page.
• Locate the number in inches you want to fill (depth) across the top of the chart.
(We recommend 2-4 inches for mulching; 12" for playground surfaces)
• The number in the column represents the number of cubic yards required.

## Base Material Calculation

The following formula is used to calculate the amount of base gravel only:

• NOTE: Base should extend 6" below your finished installation for structural purposes.
• Step 1: Length x width = total square feet of area
• Step 2: Total square feet of area x depth (inches divided by 12) = total cubic feet of area
• Step 3: Total cubic feet of area divided by 27 = total cubic yards of material needed
• Step 4: Add 10 to 20% to above calculation to allow for compaction

## Limestone Screening Calculation

The following formula is used to calculate the amount of Limestone Screening:

• Step 1: Length x width = total square feet of area
• Step 2: Total square feet of area x depth (inches divided by 12) = total cubic feet of area
• Step 3: Total cubic feet of area divided by 27 = total cubic yYards of material needed
• Step 4: Add 10 to 20% to above calculation to allow for compaction

## Jointing Sand Calculation

The following formula is used to calculate the amount of jointing sand:

• Step 1: Length x Width = total square feet of area
• Step 2: Total square feet of area + 100 (coverage of 1 bag) = total # of bags required
• Step 3: Round up to the next full bag

• NOTE: Reduce coverage of 1 bag in step #2 to 75 when calculating for a circular pattern job.

## Edging Calculations

• Step 1: Total linear feet/15 = Number of pieces required
• Step 2: Repeat step 1 for all sides requiring edging
• Step 3: Add all individual calculations
• Step 4: Round up to the next full piece count
• Step 5: Number of pieces x price per piece = cost of material

NOTE: Edging includes 4 spikes per 15 ft section.

## Miscellaneous:

• 1 acre = 43,560 square feet
• 1.3079 Cubic Yards = 1 Cubic Yard
• 2000 lbs = 1 Cubic Yard
• ' = feet
• " =inches
• radius = 1/2 diameter
