# 5 inch brick wall calculation | brickwork and brick estimate

5 inch brick wall calculation, to calculate the number of bricks required for a 5-inch thick brick wall, you’ll need to consider the wall’s height and length, as well as the size of the bricks being used.

Brick wall construction in India have different types of thickness, single row of brickwork in brick wall is 5 inch thick, double row of brickwork in brick wall is 10 inch thick and triple row of brickwork in brick wall is 15 inch thick.

In India, the standard size of 5 inch thick brick has nominal dimensions in inches are (L × W × H): 10 × 5 × 3 inches, in mm it is 250 × 125 × 75 mm, in cm it is 25 × 12.5 × 7.5 cm, in meters it is 0.25 × 0.115 × 0.075 meters and in feet it is 0.833 × 0.416 × 0.25 feet. However their actual size is 10 mm shorter than nominal size which is 9.5″ × 4.5″ × 2.75″.

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 10 inch brickwork and cement sand ratio 1:4 or 1:5 is used for 5 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 5 inch thick brick wall we have known about types of brick size used in brick wall construction, to find out number of bricks in 5 inch thick wall we have to follow following steps for brick wall calculation:-

Steps for 5 inch brick wall

● Calculate area or volume of single brick size

● To find number of bricks present in 5 inch 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 5 inch thick brick wall.

Formula for 5 inch brick wall calculation
Formula for brick calculation in 5 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 5 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 5 inch brick wall.

### 5 inch brick wall calculation per square foot

A typical nominal brick size = 10″ × 5″ × 3″, where length of brick = 10″ = 0.833 feet, width of brick = 5″ = 0.416 feet and depth of brick = 3″ = 0.25 feet.

To calculate surface area of one brick simply multiply length and height i.e area of 1 brick = 10″×3″ = 30 square inch, divide the result by 144 to find area of a brick in sq ft = 30/144 = 0.208

Given area of brickwork = 1 sq ft, so number of bricks per square foot = area of brickwork/area of a brick = 1 sq ft/ 0. 208 = 4.8 bricks.

In a typical 5 inch brick wall, there are 4.8 bricks per square foot. So, an average, a typical 5 inch thick brick wall requires 4.8 bricks for 1 square foot.

### 5 inch brick wall calculation per 100 sq ft

Given area of brickwork = 100 sq ft, so number of bricks per 100 square foot = area of brickwork/area of a brick = 100 sq ft/ 0. 208 = 480 bricks.

In a typical 5 inch brick wall, there are 480 bricks per 100 square feet. So, an average, a typical 5 inch thick brick wall requires 480 bricks for 100 square feet.

### 5 inch brick wall calculation per cubic feet

Given volume of brickwork = 1 cu ft, bricks volume = 10 × 5 × 3 = 0.833 × 0.416 × 025 = 0.0866 cubic feet. So number of bricks per cubic foot = volume of brickwork/ volume of a brick = 1 cu ft/ 0.0866 = 11.5 bricks.

In a typical 5 inch brick wall, there are 11.5 bricks per cubic foot (CFT). So, an average, a typical 5 inch thick brick wall requires 11.5 bricks for 1 cubic feet.

### 5 inch brick wall calculation per 100 cubic feet

Given volume of brickwork = 100 cubic feet, so number of bricks per 100 cubic feet = volume of brickwork/volume of a brick = 100 cu ft/ 0.0866 = 1150 bricks.

In a typical 5 inch brick wall, there are 1150 bricks per 100 cubic feet. So, an average, a typical 5 inch thick brick wall requires 1150 bricks for 100 cubic feet.

### 5 inch brick wall calculation per square meter

A typical nominal brick size = 250 × 150 × 75 mm, where length of brick = 250 mm = 0.25 m, width of brick = 150 mm = 0.15 m and depth of brick = 75 mm = 0.075 m.

To calculate surface area of one brick simply multiply length and height i.e area of 1 brick = 0.25 × 0.075 = 0.01875 square meters.

Given area of brickwork = 1 square meter, so number of bricks per square meter = area of brickwork/area of a brick = 1 m2/ 0.01875 = 54 bricks.

In a typical 5 inch brick wall, there are 54 bricks per square meter. So, an average, a typical 5 inch thick brick wall requires 54 bricks for 1 square meter.

### 5 inch brick wall calculation per 100 square meters

Given area of brickwork = 100 square meters, so number of bricks per 100 square meters = area of brickwork/ area of a brick = 100 sqm/ 0.01875 = 5400 bricks.

In a typical 5 inch brick wall, there are 5400 bricks per 100 square meters. So, an average, a typical 5 inch thick brick wall requires 5400 bricks for 100 square meters.

### 5 inch brick wall calculation per m3

Given volume of brickwork = 1 m3, bricks volume = 250 × 250 × 75 mm = 0.25 × 0.25 × 075 = 0.0028 cubic metres. So number of bricks per cubic meter = volume of brickwork/ volume of a brick = 1 cum/ 0.0028 = 355 bricks.

In a typical 5 inch brick wall, there are 355 bricks per cubic meter (m3). So, an average, a typical 5 inch thick brick wall requires 355 bricks for 1 cubic meter.

### 5 inch brick wall calculation per 100 m3

Given volume of brickwork = 100 cubic, so number of bricks per 100 cubic meters = volume of brickwork/volume of a brick = 100 cum/ 0.0028 = 35500 bricks.

In a typical 5 inch brick wall, there are 35500 bricks per 100 cubic meters. So, an average, a typical 5 inch thick brick wall requires 35500 bricks for 100 cubic meters.

Conclusion:

In a typical 5 inch brick wall, there are 4.8 bricks per sq ft, 480 bricks per 100 sq ft, 11.5 bricks per CFT, 1150 bricks per 100 CFT, 54 bricks per m2, 5400 bricks per 100 m2, 355 bricks per m3 and 35,500 bricks per 100 m3.
