Calculation of Number of Bricks for Masonry Wall

To determine the number of bricks required for a masonry wall, we need to consider the volume of the wall and the size of the bricks. Let's calculate the number of bricks required for a 100 cubic meter masonry wall.

Step 1: Determine the Volume of the Wall
The volume of the wall can be calculated using the formula:
Volume = Length x Width x Height

Given that the volume of the wall is 100 cubic meters, we need to determine the length, width, and height of the wall in meters.

Step 2: Determine the Size of the Bricks
The size of the bricks is given as 20 cm x 10 cm x 10 cm. However, we need to convert this size into meters to maintain consistency with the units used for the volume of the wall.

Converting the size of the bricks from centimeters to meters:
Length = 20 cm = 0.2 m
Width = 10 cm = 0.1 m
Height = 10 cm = 0.1 m

Step 3: Calculate the Number of Bricks
To calculate the number of bricks required, we need to divide the volume of the wall by the volume of a single brick.

Volume of a single brick = Length x Width x Height

Now, let's substitute the values into the formula:
Volume of a single brick = 0.2 m x 0.1 m x 0.1 m = 0.002 m³

To find the number of bricks required, we divide the volume of the wall (100 cubic meters) by the volume of a single brick (0.002 cubic meters).

Number of bricks required = Volume of the wall / Volume of a single brick

Number of bricks required = 100 cubic meters / 0.002 cubic meters

Number of bricks required = 50,000 bricks

Conclusion
To construct a masonry wall with a volume of 100 cubic meters using bricks of size 20 cm x 10 cm x 10 cm, we would need approximately 50,000 bricks.
