Brick Quantity Calculation in Room | How to Calculate Number of Bricks (Step-by-Step)

 

In Civil Engineering, brick quantity calculation is a very important concept for construction work. Aaj hum simple example ke through samjhenge ki ek room ke liye total number of bricks kaise calculate karte hain.

🔹 Given Data (Room Details)

👉 Length (L) = 7 m

👉 Width (W) = 5 m

👉 Height (H) = 4 m

👉 Wall Thickness = 0.25 m

👉 Door Size = 2.1 × 0.9 m

👉 Window Size = 1.8 × 2.4 m

👉 Brick Size = 19 × 9 × 9 cm

🔹 Step-by-Step Calculation

✅ 1. Long Wall Calculation

👉 Length of long wall = 7 × 2 = 14 m

👉 Volume = 14 × 4 × 0.25 = 14 m³

👉 Window deduction:

👉 14 − (1.8 × 2.4 × 0.25) = 12.92 m³

✅ 2. Short Wall Calculation

👉 Length of short wall = {5 − (0.25 × 2)} × 2 = 9 m

👉 Volume = 9 × 4 × 0.25 = 9 m³

👉 Door deduction:

👉 9 − (2.1 × 0.9 × 0.25) = 8.53 m³

🔹 3. Total Wall Volume

👉 Total Volume = 12.92 + 8.53 = 21.45 m³

🔹 4. Volume of One Brick (with mortar)

👉 Mortar thickness ≈ 10 mm

👉 Brick volume = 0.002 m³

🔹 5. Number of Bricks

👉 Number of bricks = 21.45 / 0.002

👉 = 10725 bricks

👉 Add 5% wastage:

👉 Total = 11262 bricks (approx.)

📌 Conclusion

Is example se aap easily samajh sakte ho ki brick calculation kaise ki jati hai. Ye method site par bhi use hota hai aur exams me bhi kaafi important hai.
