Let us consider single brick wall masonry as shown in the drawing for calculation purposes.
Given data:
Length of the brick wall = 16ft.
Height of the brick wall = 10ft.
The thickness of the brick wall = 0.33ft.
The total volume of the brick wall masonry
= length × height × thickness
= 16ft. × 10ft. × 0.333ft.
= 53.33 cu ft.
The total area of brick wall
= length × height
=16ft. × 10ft.
= 160 sq ft.
A. Material calculation:
Read the article "How to calculate the materials required for 4" brickworks?" before proceeding further.
No. of bricks required/ cu ft. of wall = 13.57 nos.
No. of Cement bags required/ cu ft of wall = 0.0235 bags
The volume of sand required/ cu ft. of wall = 0.1731 cu ft.
Note: The quantity of bricks, cement & sand per cu ft. is taken from the above-mentioned article.
1. No. of bricks required
= [vol. of brick wall × bricks/ cu ft.]
= [53.33 cu ft. × 13.57 nos.]
= 723.73 nos.
2. No. of cement bags required
= [vol. of brick wall × cement / cu ft.]
= [53.33 cu ft. × 0.0235 bags]
= 1.253 bags
3. The volume of sand required
= [vol. of brick wall × sand/ cu ft.]
= [53.33 cu ft. × 0.1731 cu ft.]
= 9.23 cu ft.
B. Labor calculation:
The labor rate per sq ft. of brick masonry ranges from INR 8/- to 14/- depending upon the region.
Let us consider an average rate of INR 11/- per sq ft.
The total cost of labor for 4" brick masonry
= total area of brick masonry in sq ft. × labor rate/ sq ft.
= 160 sq ft. × 11/-
= INR 1760/-
Now, let us calculate the total cost of brick masonry in table format.

Note: To get accurate results, insert your regional market rate of materials & labor, in the above table.
The cost of single brick wall masonry/sq ft.
= [total brick masonry cost ÷ total brick wall area]
= 9288.27 ÷ 160
= INR 58.05 /sq ft.
The cost of single brick wall masonry/cu ft.
= [total brick masonry cost ÷ total brick wall volume]
= 9288.27 ÷ 53.33
= INR 174.17 / cu ft.
