Volume Calculation For Slabs/Footings/Walls: Volume (m³) = Length × Width × Thickness Example: 5m × 2.5m × 0.05m = 0.625 m³ 2. Unit Conversions 1 m³ = 35.3147 ft³ 1 m³ = 1.30795 yd³ 3. Weight Calculation Weight (kg) = Volume (m³) × 2,130 kg/m³ 4. Bags Required 40kg bags: Weight (kg) ÷ 40 60lb bags: Weight (lbs) ÷ 60
