Concrete Block Calculation Formula
Wall Area = Wall Length × Wall Height
Block Area = ((Block Length + Mortar Thickness) ÷ 1000) × ((Block Height + Mortar Thickness) ÷ 1000)
Blocks Required = Wall Area ÷ Block Area
Blocks with Waste = Blocks Required × (1 + Waste Allowance ÷ 100)
Cement Bags Required = Blocks with Waste ÷ 10
Sand Bag (m³) = (Blocks with Waste × Block Length × Block Height × Mortar Thickness) ÷ 1,000,000,000
Total Cost = Blocks with Waste × Block Price (if provided)
Block Area = ((Block Length + Mortar Thickness) ÷ 1000) × ((Block Height + Mortar Thickness) ÷ 1000)
Blocks Required = Wall Area ÷ Block Area
Blocks with Waste = Blocks Required × (1 + Waste Allowance ÷ 100)
Cement Bags Required = Blocks with Waste ÷ 10
Sand Bag (m³) = (Blocks with Waste × Block Length × Block Height × Mortar Thickness) ÷ 1,000,000,000
Total Cost = Blocks with Waste × Block Price (if provided)
Standard Block: 400mm × 200mm (default dimensions)
Cement Ratio: 10 blocks per bag of cement
Sand Bag: Calculated in cubic meters (m³) based on block dimensions and mortar thickness
Note: All dimensions include mortar thickness for accurate calculations
