Working
  1. Net area = 10.00 × 3.00 − 4.0 = 26.00 m²
  2. Units per m² = 1 ÷ ((L + j) × (H + j)) = 1 ÷ ((230.0 + 10.0) × (75.0 + 10.0) mm²) = 49.02
  3. Units = 26.00 × 49.02 × 1 skin = 1,274.5; + 5% = 1339
  4. Mortar = wall volume − unit volume = 0.442 m³ (wet)
  5. Dry mortar = wet × 1.33; cement = dry ÷ 7 = 2.54 bags (126.9 kg)
