How to Calculate Concrete for Footings

Formula

Volume = Length (ft) x Width (ft) x Depth (ft)

Convert width and depth from inches to feet by dividing by 12, then divide total cubic feet by 27 for cubic yards. Footings are typically 20 inches wide and 8 inches deep for residential construction, but always follow local building codes.

हल किया गया उदाहरण

A continuous footing that is 50 ft long, 20 inches wide, and 8 inches deep.

  1. Width in feet: 20 / 12 = 1.667 ft
  2. Depth in feet: 8 / 12 = 0.667 ft
  3. Volume = 50 × 1.667 × 0.667 = 55.56 cu ft
  4. Cubic yards = 55.56 / 27 = 2.06 cu yd
  5. With 10% waste = 2.06 × 1.10 = 2.26 cu yd
