CBSE Class 4 Maths Building With Bricks Worksheet Set 03

Competency: Understanding Basic Concepts

Question 1. Tick (\(\checkmark\)) mark the face of the brick.

1. [Diagram showing a face of a brick shaped like a rectangle with diagonal dividing lines / trapezoidal perspective view] - Correct (Tick mark)
2. [Diagram showing a simple rectangle] - Incorrect
3. [Diagram showing a vertical narrow rectangle] - Incorrect
4. [Diagram showing a triangle] - Incorrect

Answer: Option 1 represents the standard flat face (front or side face) of a brick as seen in perspective view, showing the rectangular shape with inner diagonal lines representing corners.
In simple words: The face of a brick is a rectangle.

Exam Tip: A brick has six faces, and each standard face is rectangular in shape.

Question 2. Observe the following pictures and answer the question below. Which wall is stronger and why?
Answer: The wall on the left side is stronger. This is because it follows the proper alternating brick pattern (running bond), where the vertical joints are staggered so that no two vertical joints lie directly in the same vertical line in consecutive layers. The wall on the right has continuous vertical joints (vertically aligned seams), which creates a weak point where the wall can easily crack or break apart.
In simple words: The left wall is stronger because its bricks are arranged in an overlapping pattern, which distributes weight evenly.

Exam Tip: Always look for staggered joints when identifying strong brick patterns in masonry.
