## Calculator

#### How Much Material Do You Need?

Do you need to calculate the quantity of material that you need for your project? Is your area you need to cover an irregular shape? To help you calculate this, break up the area into smaller workable shapes. Measure each of them and assign them a letter. Calculate square feet for each and add the square footage together to figure total needed.

#### Rectangle

• Measure Length and Width (in feet)
• Length x Width = square feet
• Determine desired depth of material (see recommended depths and chart below)
• Square feet divided by sq. ft. per yard (from chart) = cubic yards needed
• Example: A rectangular area 16 feet long by 10 feet wide and you want 4 inches deep of stone.
• Calculations:
• 16 x 10 = 160 square feet
• 160 divided by 81 = 2 cubic yards (81 comes from the chart, 81 is how many square feet 1 cubic yard covers at a 4 inch depth)

#### Triangle

• Measure length and width of 2 sides
• Length x Width x 0.5 = square feet
• Square feet divided by sq. ft. per yard (from chart) = cubic yards needed
• Example: Given a triangle are where one side is 40 feet long, one side is 10 feet long and you want 4 inches deep of mulch or stone
• Calculations:
• 40 x 10 x 0.5 = 200 square feet
• 200 divided by 81 = 2.5 cubic yards (81 comes from the chart)

#### Circle

• Determine radius (1/2 distance of diameter or distance across)
• Square feet divided by sq. ft. per yard (from chart) = cubic yards needed
• Example: Given a circle 30 feet across (15 ft radius) and you want 3 inches deep
• Calculations:
• 15 x 15 x 3.14 = 706.5 square feet
• 706.5 divided by 108 = 6.5 cubic yards

#### Conversion Chart – Square Feet to Cubic Yards

Converts square feet to cubic yards 1 cubic yard will cover the following amount of square feet at the given depth.

• 1/4” deep 1296 square feet
• 1” deep 324 square feet
• 2” deep 162 square feet
• 3” deep 108 square feet
• 4” deep 81 square feet
• 6” deep 54 square feet
• 12” deep 27 square feet

#### Recommended Depth of Materials

• Bark Mulches 3”
• Stone less than 1″ diameter 3″
• 1-1 1/2″ Riverstone 4″
