A cubic yard is a unit of volume used extensively in the United States for major projects in construction, gardening, and other industries that require bulk material measurement. It represents a cube of space that is one yard wide, one yard long, and one yard high. Calculating cubic yards helps in estimating material delivery costs, prevents material wastage, and ensures that projects comply with budget and planning.
Formula of Cubic Yard Calculator
To assist you in different scenarios, here are formulas based on the shape of the material space:
- Rectangular or Cubic Shape:
- Volume (cubic yards) = Length (yards) x Width (yards) x Height (yards)
- Ensure all dimensions are in yards. Convert from other measurements if necessary, remembering that 1 yard = 3 feet.
- Prism (Triangular, Pentagonal, etc.):
- Volume (cubic yards) = (1/3) x Area of Base (square yards) x Depth (yards)
- This formula applies to all prism types by calculating the area of the base shape.
- Cylinder:
- Volume (cubic yards) = π x Radius² (yards²) x Height (yards)
- Use π (pi) approximately equal to 3.14159.
- Sphere:
- Volume (cubic yards) = (4/3) x π x Radius³ (yards³)
- Pyramid (Square, Triangular, etc.):
- Volume (cubic yards) = (1/3) x Area of Base (square yards) x Height (yards)
- Cone:
- Volume (cubic yards) = (1/3) x π x Radius² (yards²) x Height (yards)

Example of Cubic Yard Calculator
Imagine you’re filling a rectangular planter box. Let’s calculate how much soil is needed using the cubic shape formula:
- Measure the planter: 6 feet long, 3 feet wide, and 2 feet deep.
- Convert dimensions to yards: 2 yards long, 1 yard wide, 0.67 yards deep.
- Apply the formula: Volume = 2 x 1 x 0.67 = 1.34 cubic yards.
Most Common FAQs
A: Divide the number of feet by 3 to convert to yards. For inches, divide by 36.
A: Use laser measuring tools to ensure precise dimensions, then apply the cubic yard formulas.
A: Yes, with appropriate formulas for each geometric shape, you can calculate the volume in cubic yards.
