In this Article today we will talk about the **How to Calculate Bricks in a Wall | Brickwork Calculation Formula | How to Calculate Bricks in a Room | Bricks per square feet | How Many Bricks in 1 Cft | Brick Calculator in feet**** | How to find brick quantity in wall | How to Calculate No of Bricks in feet | Calculate bricks in 9 inch wall**

**How to Calculate Bricks in a Wall:**

The **Quantity of bricks** calculation is very important because most of the **buildings** are to be constructed with **75%** of** brickwork** especially (In the Asian countries). So it is very important for us to know how many bricks are required in one cubic feet volume.

After knowing the 1 Cft volume we can calculate the remaining quantity very easily my just multiplying 1 Cft result to the desired volume. **Brickwork Calculation Formula**

The calculation is quite simple means how many numbers of the** bricks** you will require to build your **wall** or **room** or **building**, Let us find how to calculate the **number of bricks**:

**How to Find Bricks in One Cft?**

**Length**** of Brick = ****L**** = 9” = ****0.75 ft**

**Width**** of Brick = ****W**** = 4.5” = ****0.375 ft Brickwork Calculation Formula**

**Thickness**** of Brick = ****T**** = 3” = ****0.25 ft** **Volume**** of Brick = V = ****L X W X T ****= 0.75 x 0.375 x 0.25** ** **** = ****0.070 Cft**

**No. of ****Dry** **Bricks**** in ****One CFT **** = Volume of One Cft / Volume of Brick**

**No. of Dry Bricks in One CFT = 1/0.070 ****= ****14.286 ****Bricks (Without Mortar Space)** **I want to clear you guys, 14.286 Bricks without mortar in one cft, now we should deduct the space of mortar from this quantity because we are applying bricks with mortar so we deduct 10% mortar space from 14.286 Bricks.**

**Mortar Covered ****10%**** Space = 14.286 x 10/100**

**Mortar Covered 10% Space = ****1.4286 Bricks (Mortar Space)**

**Quantity of ****Bricks with Mortar**** = 14.286 – 1.4286 = ****12.857 Bricks**

**Adding ****5% Wastage ****of Bricks = 12.857 x 5/100 = ****0.6428 Bricks**

**Hence, Brickwork Calculation Formula**

**Total No. of ****Bricks ****in ****1 Cft**** = ****Quantity of Bricks with Mortar ****+ ****5% Wastage of Bricks**

** Total No. of Bricks in 1 Cft **** = 12.857 + 0.6428**** ****= ****13.4998**

**Total ****No. of ****Bricks ****in ****1 Cft **** ****= ****13.50 (Say)**

**Hence Proved that 1 Cft = 13.50 Bricks or 100 Cft = 1350 Bricks**

**How to Find Bricks in a Wall?**

Let Take an example, The **length** of the wall = **10 ft**, **height = 6 ft**, and **thickness of the wall = 4.5 in****. Calculate bricks in 9 inch wall**

**Length of Wall** = L = **10 ft **

**Height of Wall** = H = **6 ft**

**Thickness of Wall** = T = 4.5 in = 4.5/12 = **0.375 ft **(All units should be same in feets)

Volum**e of Brickwork** = L x H x T = 10 x 6 x 0.375 = **22.50 Cft**

We know that, for **1 Cft brickwork = 13.50 Nos required (As we calculated in above)**

So, for **22.50 Cft **of brick work = 22.50 x 13.50 = 303.75** = 304 Nos. (Say)**

So, **10′ x 6′ x 4.5″** wall required **304 No. of Bricks Brickwork Calculation Formula**

**How to Find Bricks in a Room?**

**Given Data:**

**Wall 01:**

**Length of Wall 01** = L = **10 ft **

**Height of Wall 01** = H = **12 ft**

**Thickness of Wall 01** = T = 9″ = 9/12 = **0.75 ft How to Calculate Bricks in a Room**

**Wall 02:**

**Length of Wall 02** = L = **11.50 ft**

**Height of Wall 02** = H = **12 ft**

**Thickness of Wall 02** = T = 9″ = 9/12 = **0.75 ft Calculate bricks in 9 inch wall**

**Door:**

**Length of Door** = L = **4 ft**

**Height of Door** = H =** 7 ft**

**Thickness of Door** = T = 9″ = 9/12 = **0.75 ft Calculate bricks in 9 inch wall**

**Window:**

**Length of Window** = L = **5 ft**

**Height of Window** = H =** 4 ft**

**Thickness of Window** = T = 9″ = 9/12 = **0.75 ft**

**Solution:**

**Volume of Walls:**

Volume of **Wall 01** = L x H x T = 10 x 12 x 0.75 = **90.00 Cft**

Volume of **Wall 02** = L x H x T = 11.50 x 12 x 0.75 = **103.50 Cft**

**Total Volume of Walls = Volume of Wall 01 + Volume of Wall 02**

**Total Volume of Walls** = 90 + 103.50 = **193.50 Cft**

**Volume for Deduction (Door + Window):**

Volume of **Door** = L x H x T = 4 x 7 x 0.75 = **21.00 Cft**

Volume of **Window** = L x H x T = 5 x 4 x 0.75 = **15.00 Cft**

**Total Volume for Deduction = Volume of Door + Volume of Window**

**Total Volume for Deduction** = 21.00 + 15.00 = **36.00 Cft**

**Net Volume:**

**Net Volume = Total Volume of Walls – Total Volume for Deduction**

**Net Volume** = 193.50 – 36 = **157.50 Cft**

**No. of Bricks Calculation:**

No. of **Bricks** in one Cft = **13.50 Bricks**

**Total No. of Bricks = Net Volume x 13.50**

**Total No. of Bricks **= 157.50 x 13.50 = 2126.25 Bricks =** 2127 Bricks (Say)**

**Hence, the total No. of Bricks used in Construction of Room are 2127 Bricks**

**How to Find Bricks in a Building?**

**Length of Wall 0**1 = 0.75′ + 8′ + 0.75′ + 8′ + 0.75′ =** 18.25′**

**Length of Wall 02** = **16.75′** (As given)

**Thickness of Wall** = 9″ = **0.75′** (As given) **Bricks per square feet**

**Brickwork in Foundation:**

**Volume of B/W in Wall 01 (Step-I)** = L x B x H = 19′ x 1.50′ x 0.50′ = **14.25 Cft** (Where, Length of Wall = 1.5′ – 0.75′ + 18.75′ = 19′ for adding offset in foundation)

**Volume of B/W in Wall 01 (Step-II)** = L x B x H = 18.625′ x 1.125′ x 0.50′ = **10.477 Cft** (Where, Length of Wall = 1.125′ – 0.75′ + 18.75′ = 18.625′ for adding offset in foundation) **How to find brick quantity in wall**

**Total Volume of B/W in Wall 01** = 14.25 + 10.477 = **24.727 Cft**

**Volume of B/W in Wall 02 (Step-I)** = L x B x H = 16′ x 1.50′ x 0.50′ = **12.00 Cft** {Where, Length of Wall = 16.75′ – (1.50′ – 0.75′) = 16′ for subtracting offset in foundation because this offset is already included in wall 01 Step-I B/W)

**Volume of B/W in Wall 02 (Step-II)** = L x B x H = 16.375′ x 1.125′ x 0.50′ = **9.211 Cft** (Where, Length of Wall = 16.75′ – (1.125′ – 0.75′) = 16.375′ for subtracting offset in foundation because this offset is already included in wall 01 Step-II B/W)

**Total Volume of B/W in Wall 02** = 12.00 + 9.211 = **21.211 Cft Bricks per square feet**

**Brickwork in Super Structure:**

**Volume of B/W in Wall 01** = L x B x H = 18.25′ x 0.75′ x 12′ = **164.250 Cft**

**Volume of B/W in Wall 02** = L x B x H = 16.75′ x 0.75′ x 12′ = **150.750 Cft**

**Total Volume of B/W in Walls** = 164.250 + 150.750 = **315.00 Cft Bricks per square feet**

**Total Brickwork in Building:**

**Total B/W in Building** = 24.727 + 21.211 + 315.00 = **360.938 Cft Bricks per square feet**

**Brickwork Deduction for Doors and Windows:**

**Volume of B/W in Door D1** = No x L x B x H = 1 x 4′ x 0.75′ x 7′ = **21.00 Cft**

**Volume of B/W in Door D2** = No x L x B x H = 2 x 3′ x 0.75′ x 7′ = **31.500 Cft**

**Volume of B/W in Window W1** = No x L x B x H = 2 x 5′ x 0.75′ x 4′ = **30.00 Cft**

**Volume of B/W in Window W2** = No x L x B x H = 6 x 4′ x 0.75′ x 4′ = **72.00 Cft**

**Total Deduction for Doors and Windows** = 21.00 + 31.50 + 30.00 + 72.00 = **154.50 Cft Brick Calculator in feet**

**Net Brickwork:**

**Net Brickwork in Building = Total Brickwork in Building – Deduction for Doors and Windows**

**Net Brickwork in Building** = 360.938 – 154.50 = **206.438 Cft Brick Calculator in feet**

**No. of Bricks Calculation:**

**No. of Bricks** = Net Brickwork x 13.50 = 206.438 x 13.50 = 2786.906 = **2787 Bricks (Say) Brick Calculator in feet**

**Hence, Total No. of Bricks used in Building Construction are 2787**

**single block wall**requires**10 blocks per square metre**. - So the total number of blocks for the wall is:
**wall height (metres) x wall length (metres) x 10 = number of blocks****Brick Calculator in feet**

**Example for Brickwork:**

**Quantity for Brick Wall:** *9m2 (surface area) x 60 (half-brick thick wall) = 540 bricks*

**Two single Brick Piers:** *1.5m (vertical height) x 14 = 42 bricks*

**Wastage of 10%:** *58.2 bricks*

**Total Bricks Needed:** *640.2 bricks needed How to find brick quantity in wall*

**Example for Blockwork:**

**Wall Size =** 3000 mm x 440 mm x 1500 mm

**Quantity of Blocks** = L x H x 10 = 3.0 x 1.50 x 10 = 45 Blocks

**No of Blocks = 45 Blocks How to find brick quantity in wall**
