How to calculate sand
Sand is sold by volume or by weight. For a rectangular area, multiply length by width by depth, with everything in feet, then convert to cubic yards by dividing by 27. To get tons, multiply cubic yards by 1.3.
Formula: cubic yards = length (ft) × width (ft) × depth (in ÷ 12) × (1 + waste %) ÷ 27, and tons = cubic yards × 1.3
Worked example: 20 ft × 10 ft × 4 in area
Volume = 20 × 10 × (4 ÷ 12) = 66.7 ft³. Add 10% waste: 73.3 ft³. Divide by 27: 2.72 cubic yards, which is 3.5 tons.
Which sand?
Use washed concrete sand for paver beds and mixes. Play sand is finer and packs too tight for construction work.
