Wall 12.00 m² × 225 mm

  • Bricks 1,494 bricks 1,422 + 5% wastage
  • Cement 5 bags 4.23 bags for 1:5 mortar
  • Sand 0.26 cubes 0.73 m³
  • Mortar (wet) 0.66 m³
How we calculated this
  1. Wall area 4 × 3 = 12.00 m²
  2. Wall volume 12.00 × 0.225 = 2.70 m³
  3. Brick with mortar 0.225 × 0.113 × 0.075 = 0.001898 m³
  4. Bricks 2.70 ÷ 0.001898 = 1,422; +5% = 1,494 bricks
  5. Wet mortar 2.70 − 1,422 × 0.001432 = 0.663 m³
  6. Dry mortar 0.663 m³ × 1.33 = 0.881 m³
  7. Cement 0.881 ÷ 6 × 1440 kg/m³ ÷ 50 kg = 4.23 bags
  8. Sand 0.881 × 5/6 ÷ 2.832 = 0.26 cubes

Estimates are for budgeting and checking quotes, not structural design. Have a qualified engineer confirm quantities and reinforcement before building.
