Working
  1. Internal walls: 450.0 m² × 12 mm = 5.400 m³ wet × 1.27 = 6.858 m³ dry → cement 28.22 bags, sand 5.878 m³
  2. External walls: 220.0 m² × 20 mm = 4.400 m³ wet × 1.27 = 5.588 m³ dry → cement 32.19 bags, sand 4.470 m³
  3. Ceilings: 120.0 m² × 6 mm = 0.720 m³ wet × 1.27 = 0.914 m³ dry → cement 6.58 bags, sand 0.686 m³
