Calculate total volume, surface coverage, and conversion between cubic meters, yards, and cubic feet.
Geometric breakdown showing how length, width, and depth determine cubic yards and CFT.
Illustrates how surface dimensions and depth multiply to determine exact cubic feet, cubic yards, and metric tonnage.
Engineering calculations used to estimate rectangular, circular, and bulk sand requirements.
Converts all measurements to uniform units (feet or meters) before computing volume.
Calculates sand volume for circular pits, sandbox rings, round swimming pools, and round tanks.
Converts calculated cubic feet into standard contractor yards and dry sand metric tons.
Sand volume calculation is the foundational step for any construction, landscaping, or paving project. The basic formula is straightforward: Area × Depth = Volume.
Loose sand compacts by approximately 5% to 15% when settled or tamped. Always add a 5–10% safety margin for wastage and grading unevenness.
Common questions about sand volume calculations, cubic yard formulas, and unit conversions.
To calculate sand volume in cubic yards, multiply your Total Area (sq ft) × Depth (inches) ÷ 324. For example, a 10 ft × 10 ft patio (100 sq ft) with a 2-inch sand bed requires: 100 × 2 ÷ 324 = 0.62 cubic yards.
There are exactly 27 cubic feet (CFT) in 1 cubic yard (3 ft × 3 ft × 3 ft). In metric volume, there are 35.315 cubic feet (CFT) in 1 cubic meter (m³). 1 cubic meter equals approximately 1.308 cubic yards.
For circular areas, use the cylinder volume equation: Volume = π × (Diameter ÷ 2)² × Depth. For example, an 18-foot round above-ground pool with a 2-inch sand bed requires: 3.1416 × 9² × (2 ÷ 12) = 42.4 CFT = 1.57 cubic yards.
Always add a 10% to 15% contingency factor to your geometric calculation. Loose sand reduces in volume when tamped or roller-compacted, and spillage occurs during hauling and grading.
