Hello friends, welcome to another article. Today we are going to discuss **How many bricks required for 10×10 wall and 10×10 room 4.5 & 9 inch brick walls.** As we know, before the construction of any building, if we know the amount of material used in it, then how easy the work becomes. Here you will know the calculation of bricks for a 100 sq. ft area and we got this result practically. It will help you to find the exact number of bricks required for a 10×10 (100 sq ft) area for 4.5 & 9-inch thick brick walls.

As we know that there are many sizes of bricks. But the standard sizes bricks are called modular bricks. The arrangement of bricks in rows is called courses. Bricks are set one above the other with the help of cement mortar. To build a structure such as a brick wall. Red brick and AAC(autoclave aerated concrete) blocks are used in the construction of the wall.

### What are Bricks?

Clay is kneaded with the help of water and after giving it a rectangular shape, it is made hard by baking it in a fire, it is called a brick. Bricks are used in the construction of a building.

On the basis of the thickness of the brick wall, there are mainly three types of brick wall construction. i.e 4.5 inches,9 inches, and 13.5-inch brick walls.

But 4.5-inch and 9-inch brick wall is the most popular nowadays in the construction of low and high-rise commercial and residential building. The 13.5-inch brick wall is mainly used in some villages these days. It is used in villages as an RCC column and it is a very low budget compared to the RCC column.

Now we are going to calculate the number of bricks for a 10×10 room size and the needed quantity of cement and sand. The size of the wall can be 4.5 inches, 9 inches, and 13.5 inches.

## How many bricks are required for a 10×10 wall and 10×10 room 4.5 & 9 inch brick wall

Lets we assume that the height of the room = 10 foot.

And the area of a single wall = 10×10 = 100 sq ft.

So, the area of four walls =100 sq ft × 4 = 400 sq ft.

Note- The area of door, window, and ventilation have not been included.

So, let us assume the door size = 7 × 3 = 21 sq ft.

Let us assume the window size = 4 × 3 =12 sq ft.

Ventilation size = 1×1 =1 sq ft.

So the total deducted area will be = (21+12+1)sq ft=34 sq ft.

Therefore, the net area for the brick wall will be 400sq ft – 34 sq ft = 366 sq ft.

We have got the net area for brickwork = 366 sq ft.

As we have thicknesses for 4.5-inch, 9-inch, and 13.5-inch brick wall.

### How many bricks required for 10×10 room 4.5-inch thick brick wall

As we have a brickwork area = 366 sq ft.

Where the size of the brick wall = 4.5 inch

And a brick size =(8 × 4 × 4) inch .

And the mortar thickness = 0.5 inches or 12mm.

Size of the brick after mortar mix will be = (8.5 × 4.5 × 4.5)inch.

Brickwork volume = (brickwork area × size of the brick wall) ÷ mortar thickness in mm.

Brickwork volume = (366 × 4.5) ÷ 12 = 137.25 cubic ft.

Volume of 1 brick with mortar = (8.5 inch /12) × (4.5 inch /12) × (4.5 inch/12)

= 0.0996 cubic ft.

The number of bricks = volume of brickwork ÷ volume of 1 brick with mortar mix.

=137.25 ÷ 0.0996=1378.

But remember that about 2 % of bricks may be broken or wasted while Transportation and other reasons.

So, 2 % of 1378 = 27.56 = 28 around 28 bricks more should be considered to the total.

Therefore, 1378 + 28 =1406 bricks.

So it is clear that 1406 bricks need for the construction of a 10×10 room 4.5-inch brick wall.

### How many bricks required for 10×10 room of 9-inch thick brick wall.

As we have a brickwork area = 366 sq ft.

Where the size of brickwall = 9 inch, And a brick size = (8 × 4 × 4) inches.

And the mortar thickness = 0.5 inches or 12mm.

The size of the brick after adding mortar thickness will be = (8.5 × 4.5 × 4.5) inch.

Brickwork volume = brickwork area × size of brick wall mortar thickness in mm.

= 366 × 9/12 = 274.5 cubic ft.

Volume of 1 brick with mortar = (8.5 inch /12) × (4.5 inch /12) × (4.5 inch/12)

= 0.0996 cubic ft.

Number of bricks = volume of brickwork ÷ volume of 1 brick with mortar mix.

= 274.5 ÷ 0.0996 = 2756.

But remember that about 2 % of bricks may broken or wastes while Transportation and other reasons.

So, 2 % of 2756 = 55 bricks more should be considered to the total.

Therefore, 2756 + 55 = 2811 bricks.

So it is clear that 2811 bricks need for the construction of a 10×10 room of 9 inch brickwall.

### How many bricks required for 10×10 room of 13.5 inch brickwall.

As we have a brickwork area = 366 sq ft.

Where the thickness of the brick wall = 13.5 inch

And a brick size = (8 × 4 × 4)inch.

And the mortar thickness = 0.5 inches or 12mm.

Size of brick after mortar mix will be = (8.5 × 4.5 × 4.5)inch.

Brickwork volume = brickwork area × size of brick wall ÷ mortar thickness in mm.

= (366 × 13.5) ÷ 12 = 412 cubic ft.

Volume of 1 brick with mortar = (8.5 inch /12) × (4.5 inch /12) × (4.5inch/12) = 0.0996 cubic ft.

Number of bricks = volume of brickwork ÷ volume of 1 brick with mortar mix.

= 412 ÷ 0.0996 = 4134 bricks.

But remember that about 2 % of bricks may break or waste while Transportation and other reasons.

So, 2 % of 4134 = 83 bricks more should be considered in the total.

Therefore, 4134 + 83 = 4217 bricks.

So it is clear that 4217 bricks need for the construction of a 10×10 room with a 13.5-inch brick wall.

### How many bricks are required for a 10×10 wall of 4.5-inch thick brick wall

Now let us assume the net area for brickwork =100 sq ft.

Where the thickness of the brick wall = 4.5 inches.

And a brick size = (8 × 4 × 4)inch.

And the mortar thickness = 0.5 inches or 12mm.

The size of the brick after-mortar mix will be = (8.5 × 4.5 × 4.5)inch.

Brickwork volume = brickwork area × size of the brick wall ÷ mortar thickness in mm.

= 100 × (4.5/12) = 37.5 cubic ft.

The volume of 1 brick with mortar = (8.5/12) × (4.5/12) × (4.5/12)

= 0.0996 cubic ft.

The number of bricks = volume of brickwork ÷ volume of 1 brick with mortar mix.

=37.5/0.0996=376 bricks.

But remember that about 2 % of bricks may be broken or wasted while Transportation and other reasons.

So, 2 % of 376 = 8 bricks more should add to the total.

Therefore, 376 + 8 = 384 bricks.

So it is clear that 384 bricks need for the construction of a 10×10 (100 sq ft) area of 4.5-inch brick wall.

### 10×10 room estimate and construction cost of brick work

Total area for brickwork = 366sq ft. (Door, window, and ventilator are not included).

Wall thickness = 9 inches.

Brickwork volume = 366 × (9/12) = 274.5 cubic ft.

1 brick volume with mortar = (8.5 inch/12) × (4.5 inch/12) × (4.5 inch/12)

1 brick volume with mortar = 0.0996 cubic ft.

The number of bricks = Volume of brickwork ÷ 1 brick volume with mortar.

= 274.5 ÷ 0.0996 =2756

But remember that about 2 % of bricks may be broken or wasted while Transportation and other reasons.

2% of 2756 = 55 bricks.

Therefore 2756 + 55 = 2811 bricks.

So it is clear that 2811 bricks need for the construction of a 10×10 room with 9-inch brick wall.

### Required Material cost of 10×10 ft room

Let us assume that the market rate of bricks = 8 rupees per brick.

Then the total cost of bricks will be = 8 × 2811= 22488 Rupees.

Volume of 1 brick = (8″/12) × (4″/12) × (4″/12) = 0.0741 cubic ft. So the volume of all bricks = 0.0741 × 2811= 208.2 cubic ft.

Volume of mortar = brickwork volume – the volume of all bricks.

= 274.5 – 208.2 = 66.3 cubic ft.

Here we got the wet volume of mortar = 66.3 cubic ft.

To convert the wet volume into the dry volume we need to multiply by 1.33 in the wet volume of mortar.

Dry volume = 66.3 × 1.33 = 88 cubic foot = 2.5 cubic meter.

The ratio of cement and sand for brickwork =1:5.

Quantity of cement = (1/6) × 2.5 m^{3} × 1440 kg/m^{3}.

= 598 kg.

1 bag of cement contains 50 kg So, 598 ÷ 50 = 11.96 =12 bags.

If the rate of cement is rs.450 per bag in the market. then the cost of the cement will be 12 × 450 = 5400 Rupees.

Sand quantity = 5/6 × 88 =74 cubic ft. let the sand rate will be rs.70 per cubic foot. So, the cost of the sand will be =70 × 74 = 5180 Rupees.

Therefore, the total estimated cost for brickwork material and construction of 10 × 10 rooms.

Bricks cost = rs. 22488 , cement cost = rs.5400 , sand cost = rs.5180.

Total cost = 22488 + 5400 + 5180 = 33068 Rupees.

So, here we have the total expense amount for the construction of brickwork. But the labor charge, cost of plastering, and Cost of RCC are not included.

#### Conclusion

In this article, we have discussed the calculation of bricks required for a 10×10 room. The cost of brick walls for 4.5 inches and 9-inch brick walls. The cement and sand costs also discussed for a 100 sq ft area.
