One man want to build a wall .The length and breadth of the wall are 2...
Given information:
- Length of the wall = 20 centimeters
- Breadth of the wall = 30 centimeters
- Number of bricks required for 1 square centimeter = 35
To find:
- Number of bricks required to build the wall
Calculation:
To calculate the number of bricks required to build the wall, we need to find the total area of the wall and then multiply it by the number of bricks required for one square centimeter.
Step 1: Calculate the area of the wall
The formula to calculate the area of a rectangle is:
Area = Length * Breadth
Substituting the given values:
Area = 20 * 30
Area = 600 square centimeters
Step 2: Calculate the number of bricks required
To find the number of bricks required, we multiply the area of the wall by the number of bricks required for one square centimeter.
Number of bricks required = Area * Number of bricks per square centimeter
Number of bricks required = 600 * 35
Number of bricks required = 21,000
Answer:
Therefore, the man needs 21,000 bricks to build the wall. Hence, the correct answer is option 'C'.
