How the formula works
Volume = L × W × T | Steel = Volume × Steel Density | Shuttering = 2 × (L × T + W × T) + L × W
- Concrete Volume = Length × Width × Thickness
- Steel Quantity = Concrete Volume × Steel Density (kg/m³)
- Shuttering Area = 2 × (L × T + W × T) + L × W (bottom + sides)
- Slab Area = Length × Width
- Total Cost = (Concrete Volume × Price per m³) + (Steel Quantity × Price per kg)
