Introduction to CBSE Class 6 Mathematics Chapter "Measurement and Mensuration"
In this chapter, students will explore the fascinating world of mensuration, beginning with the basics of measurement. It guides them through different units of measurement and the conversion between them, such as length (millimeters, centimeters, meters, and kilometers), mass (grams and kilograms), and capacity (liters and milliliters). Students learn to calculate the area and perimeter of simple geometrical figures like squares, rectangles, and triangles, laying the groundwork for more complex geometrical concepts.
The chapter provides practical applications and problem-solving exercises, emphasizing the importance of accuracy in measurement. It introduces the concept of the area as the amount of surface a shape covers and the perimeter as the total distance around a shape. With clear explanations and illustrative examples, students get to grips with these foundational concepts that are crucial for their mathematical progression.

Questions and Answers for CBSE Class 6 Mathematics Chapter "Measurement and Mensuration"
- Q1: Why do we need to learn about different units of measurement? ANS: Learning about different units of measurement is essential for accurately describing and converting quantities in everyday life and scientific applications.
- Q2: How do you convert centimeters to meters? ANS: To convert centimeters to meters, divide the number of centimeters by 100, since one meter equals 100 centimeters.
- Q3: What is the area, and how is it calculated for a rectangle? ANS: The area is the measure of the surface a shape covers. For a rectangle, it is calculated by multiplying its length by its width.
- Q4: How do you find the perimeter of a square? ANS: The perimeter of a square is found by multiplying the length of one side by four, as all sides of a square are equal in length.
- Q5: What is the formula to calculate the area of a triangle? ANS: The area of a triangle is calculated by multiplying the base by the height and then dividing by two (Area = 1/2 × base × height).
- Q6: Why is mensuration important in real life? ANS: Mensuration is important in real life for various tasks such as construction, interior design, creating maps, sewing, and any task that requires area and volume calculations.
- Q7: How does estimation play a role in measurement? ANS: Estimation helps to make quick, reasonable predictions about measurements when exact values are not needed or practical.
- Q8: Can you measure the capacity of a solid object? ANS: The capacity usually refers to the volume of space inside a container and is not used for solid objects. For solids, we measure the volume, not capacity.
- Q9: What is meant by the ‘metric system’ of measurement? ANS: The metric system is an international decimal system of measurement that uses units such as meters for length, kilograms for mass, and liters for capacity.
- Q10: How is measuring the area of an irregular shape different from measuring a regular shape? ANS: Measuring the area of an irregular shape can be more complex and may involve dividing the shape into regular shapes and summing their areas or using other specialized methods.
