How Much Bulk?

Bulk Material Calculator

How to figure how much bulk material you need

Rectangle – Length x width x depth – divided by 27 = cubic yards
Example:  10 ft x 10 ft x .5 ft (6 inches) divided by 27 = 1.85 cubic yards

Triangle – Length x width x .5 = square feet
Example:  10 ft x 10 ft x .5 = 50 sq ft
Use conversion chart below (square feet to cubic yards)

Circle – Radius (1/2 the diameter) x 3.14 = square feet
Example:  10 ft radius x 3.14 = 31.4 sq ft
Use conversion chart below (square feet to cubic yards)

 

Conversion Chart (square feet to cubic yards)
1 yard covers at a depth of:
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
12″ deep – 27 square feet

 

Volumes
Heaping load on a full size pickup is about 3 cubic yards
Max load on a small pickup is about 1 1/2 cubic yards

Small single-axle dump truck load is 5 yards
Big dump trucks are 10 to 15 yards
27 cubic feet in one cubic yard is 3′ x 3′ x 3′
One cubic yard = 9 square feet (3′ x 3′)
There are 21 bushels in one cubic yard

 

Recommended Depth of Materials
Topsoil in lawns – minimum 4″
Lawn topdressing – 1/4″
Garden soil in flowerbeds – 6-12″
Bark mulches – 3″
Stone less than 1″ in diameter – 3″
