How to calculate bricks in 9 inch wall for 1 sq.ft and how do I find the quantity of bricks in 9 inch brick wall**. **in this topic we know how many bricks in 1 square feet (sq. ft) and 100 square feet for 9 inch brick wall.

We know that bricks have irregular shape and size and their measurement vary according to different nation but in this topic we measured according to indian standard size of brick that is used in standard calculation.

According to indian standard size of brick have **dimension 9″×4.5″×3″**

What is thickness of cement mortar,in brickwork cement mortar is used for adhesive material and increasing their strength depends on mortar thickness. Thickness of cement mortar in brickwork is about 0.4″ to 0.5″ (10 to 12 mm)is being used.

More than 0.5″ thickness of mortar cement reduce the strength of brick wall so it might not be used. So we should apply only cement mortar thickness of 0.4″ to 0.5″ in brickwork. More than 0.4″ to 0.5″ and less than decrease the strength of brick wall.

**How many bricks required for 9 inch brick wall**

Brickwork is masonry work produced by a bricklayer, using bricks and mortar ( mixture of cement and sand in fix ratio). Generally cement mortar ratio 1:6 is used for 9 inch & 13.5 inch brickwork and cement sand ratio 1:4 or 1:5 is used for 4.5 inch or 4 inch thick brick wall. Typically, rows of bricks called courses are laid on top of one another to build up a brick wall structure.

Brick calculation in 9 inch thick brick wall we have known about types of brick size used in brickwall construction, to find out number of bricks in 9 inch thick wall we have to follow following steps for brick wall calculation:-

**Steps of brick calculation for wall**

● Calculate area or volume of single brick size

● for find out number of bricks present in brick wall divide the given area or volume of brickwork by area or volume of single brick

● space cover by mortar in brickwork is 10% so deduct this from number of bricks

● about 5% of bricks are wastage during transportation,storage and brick laying work, so add this number into number of bricks

● by adding wastage number of bricks, you have got total number of brick required for 9 inch thick brick wall.

**Formula for brick calculation in 9 inch brick wall**

Formula for brick calculation in 9 inch thick brick wall depends on given area or volume of brickwork and size of brick. So formula for number of brick calculation is

Number of bricks = (area of brickwork/area of 1 brick) + (5 % wastage _ 10% mortar)

This formula for brick calculation is used for number of bricks per square foot or per square metre for 9 inch brick wall

Number of bricks = (volume of brickwork/volume of 1 brick) + (5 % wastage _ 10% mortar)

This formula for brick calculation is used for number of bricks per cubic foot or per cubic metre for 9 inch brick wall.

**How many bricks in 1 square feet for 9 inch brick wall**

***Given**:- we have given following measurement

Size of one brick=9″ ×4.5″ ×3″

( according to indian standard size)

Area of brick wall = 1 sq.ft

Thickness of cement mortar=0.5″

Thickness of brick wall=9″

Step of brick calculation per sq. ft

1) first we should add mortar thickness in indian brick size

2)second we calculate volume of brick with mortar

3) third we should calculate volume of brick wall

4) forth we should calculate number brick by dividing brick wall volume by volume of one brick with mortar

5) considering 5 to 10% of wastage

Calculation for how many bricks in 1 square feet

1)We have to add cement mortar thickness that is 0.5″ in each measurement of brick dimension.

Size of one brick with mortar

=9″×4.5″×3″ brick size

=(9″+0.5″)×(4.5″+0.5″)×(3″+0.5″)

=9.5″×5″×3.5″ brick size with mortar

2) volume of one brick with mortar

=9.5″×5″×3.5″ =166.25 cubic inch

3) volume of brick wall

=Area × thickness of brick wall

=1 sq.ft ×9″ (1sq.ft =144 square inch)

= 144″×9″ =1296 cubic inch

4) Number of brick= volume of brick wall/ volume of 1 brick with mortar

Number of brick=1296/166.25 =7.8 nos

5) considering 5 to 10% wastage of brick during transportation and storage

10% wastage brick =0.78 nos

6) get the total number of brick

= 7.8+0.78 = 8.58 nos

8.58 nos bricks present in 1 square feet for 9 inch brick wall.

**How many bricks in 100 square feet for 9 inch brick wall**

*Solve:-

1 sqft 9″ brick wall have 8.58 brick so

For 100 sq.ft

=8.58×100 = 858 number of bricks.

858 nos bricks are present in 100 square feet for 9 inch brick wall

**How many bricks in 1000 square feet for 9 inch brick wall**

Solve:-

1 square feet 9 inch brick wall have 8.58 brick so for 1000 sq.ft

= 1000×8.58 =8580 number of bricks.

8580 nos bricks are present in 9 inch brick wall of 1000 sqft

Now another type of bricks calculation to find out how many bricks in 1 square foot and 100 square foot for 9 inch brick wall

**Brick calculation per sq ft for 9 inch brick wall**

Indian brick size = 9″ × 3″ ×4.5″

Where length of brick = 9″ = 0.75 feet

Width of brick = 4.5″ = 0.375 feet

Depth of brick = 3″ = 0.25 feet

Area of 1 brick = 9″×3″ = 27 square inch

Area of brick in sq ft = 0.75′ × 0.25′ = 0.1875

Given area of brickwork = 1 sq ft

Number of bricks = area of brickwork/area of brick

No. of bricks = 1 sqft/0.1875 = 5.34

Consider 10% space cover by mortar deduct this value in number of bricks

10% of 5.34 = 0.534

Now no. of bricks = 5.34 _ 0.534 = 4.806

Consider 5% wastage of bricks in transportation, storage and doing brickwork so add this value in number of brick

5% of 5.34 = 0.267

No. of bricks = 4.806 + 0.267 = 5.073

5.073 nos bricks present in per square feet (sq ft) for 4.5 inch thick brick wall

In 9 inch brick wall = 5.073 ×2 = 10.146 nos

10.146 nos bricks present in per square feet (sq ft) for 9 inch thick brick wall

**Brick calculation for 100 square feet in 9 inch brick wall**

10.146 nos bricks present in per square feet (sq ft) for 9 inch thick brick wall

1 sq ft = 10.146 nos bricks

100 sq ft = 10.146 × 100 = 1014.6 nos bricks

1014.6 nos bricks present in 100 square feet (sq ft) for 9 inch thick brick wall
