Short Answer Questions
1. Rohan's rope is longer. (5 m = 500 cm). It is longer by 150 cm (500 cm - 350 cm).
2. 3 m = 300 cm. Remaining length = 300 cm - 80 cm = 220 cm.
3. 50 mm = 5 cm. Total distance = 5 cm + 6 cm = 11 cm.

FAQs on Metric Units of Length Worksheet for Class 3: m, cm, mm
1. What are the metric units of length for Class 3?
The main metric units of length for Class 3 are meter (m), centimeter (cm), and millimeter (mm). These standard units are used to measure the length of different objects and distances.
- Meter (m): Used for longer lengths, like the height of a door.
- Centimeter (cm): Used for shorter lengths, like the length of a pencil.
- Millimeter (mm): Used for very small lengths, like the thickness of a notebook.
2. How do you convert cm to m for Grade 3?
To convert centimeters (cm) to meters (m), you need to know the basic conversion rule: 100 cm = 1 m. For Class 3 students, the easiest way to understand this is to divide the number of centimeters by 100. For example, 200 cm is equal to 2 m.
3. How many mm are in a cm?
There are 10 millimeters (mm) in 1 centimeter (cm). This is a fundamental concept in the Class 3 Maths metric units topic. You can see these 10 small marks between any two centimeter numbers on a standard ruler.
4. What is the smallest metric unit of length taught in Class 3?
The smallest metric unit of length typically taught in Class 3 is the millimeter (mm). It is part of the metric system and is used for measuring very small objects with precision, such as the width of a pencil lead.
