✅How To Calculate CC Road Construction Cost Estimate Given Data : Length : 450 ft. Breadth : 20 ft. Thickness : 6 inches = 0.5 ft. Mix Ratio : M20 ( 1:1.5:3 ) 📌Calculation Of Volume 1m³ = 35.3147 ft³ Volume = Length ⨯ Breadth ⨯ Thikness = 450 ⨯ 20 ⨯ 0.5 = 4500 ft³ Convert Cubic meter : Volume in m³ = 4500 / 35.3147 ≈ 127.45 m³ 📌Concrete Mix & Material Quantities M20 Grad Concret ( 1:1.5:3 mix ) = 5.5 Dry Volume = Wet Volume ⨯ 1.54 = 127.45 ⨯ 1.54 = 196.27 m³ 📌Calculet Material Quantity (m³) ◾
