Number of bricks required for one cubic metre of brick masonry

To calculate the number of bricks required for one cubic metre of brick masonry, we need to consider the following factors:

1. Size of brick: The standard size of a brick is 190 mm x 90 mm x 90 mm.

2. Size of mortar joint: The standard size of a mortar joint is 10 mm.

3. Volume of one brick: The volume of one brick can be calculated as follows:

Volume of one brick = Length x Breadth x Height
= 0.19 m x 0.09 m x 0.09 m
= 0.001539 m^3

4. Volume of one brick with mortar joint: The volume of one brick with mortar joint can be calculated as follows:

Volume of one brick with mortar joint = (Length + Thickness of mortar joint) x (Breadth + Thickness of mortar joint) x Height
= (0.19 m + 0.01 m) x (0.09 m + 0.01 m) x 0.09 m
= 0.00198 m^3

5. Volume of one cubic metre of brick masonry: One cubic metre of brick masonry consists of 500 bricks and 0.3 cubic metres of mortar.

Volume of one cubic metre of brick masonry = (500 x 0.00198 m^3) + 0.3 m^3
= 0.99 m^3

6. Number of bricks required for one cubic metre of brick masonry: The number of bricks required for one cubic metre of brick masonry can be calculated as follows:

Number of bricks required = Volume of one cubic metre of brick masonry / Volume of one brick with mortar joint
= 0.99 m^3 / 0.00198 m^3
= 500

Therefore, the correct option is D, i.e., 500 bricks are required for one cubic metre of brick masonry.

1m = 100 cm nominal size of brick 20cm* 10cm* 10cm No. of bricks in one cubic meter = (100*100*100)/ (20*10*10)= 500 Therefore no. bricks in one cumec is 500..
