What is it?

Width tells us how broad or thick something is from one side to the other. When we talk about the 'widest' object, we are looking for the object that has the greatest distance across its shortest dimension.

Simple Example

Quick Example

Imagine you have three different cricket bats. One bat is 10 cm wide, another is 11 cm wide, and a third is 9 cm wide. The bat that is 11 cm wide is the widest among them.

Worked Example

Step-by-Step

Let's find the widest among these everyday items:

Step 1: Look at the width of a mobile phone. Let's say it is 7 cm wide.
---Step 2: Now, look at the width of a school notebook. Let's say it is 18 cm wide.
---Step 3: Next, consider the width of a tiffin box. Let's say it is 15 cm wide.
---Step 4: Compare all the widths: 7 cm (mobile phone), 18 cm (notebook), 15 cm (tiffin box).
---Step 5: Identify the largest number among 7, 18, and 15.
---Step 6: The largest number is 18.
---Answer: The school notebook is the widest among the three items.

Why It Matters

Understanding width is crucial in many fields, from designing buildings to fitting furniture. Architects use it to plan room sizes, while engineers use it to design roads and bridges. Even tailors use width measurements to make clothes that fit perfectly.

Common Mistakes

MISTAKE: Confusing width with length or height. | CORRECTION: Width is specifically the measurement across an object, usually the shorter side, while length is typically the longer side, and height is how tall something is.

MISTAKE: Not using the same unit of measurement when comparing widths. | CORRECTION: Always make sure all widths are measured in the same units (e.g., all in cm, or all in meters) before comparing them to find the widest.

MISTAKE: Only comparing two items when there are many. | CORRECTION: To find the widest among a group, you must compare the width of every single item in that group.

Practice Questions

Try It Yourself

QUESTION: Which is widest: a pencil (0.8 cm), a pen (1.2 cm), or a marker (1.5 cm)? | ANSWER: The marker is widest (1.5 cm).

QUESTION: A road has three lanes. Lane 1 is 3.5 meters wide, Lane 2 is 4 meters wide, and Lane 3 is 3.8 meters wide. Which lane is the widest? | ANSWER: Lane 2 is the widest (4 meters).

QUESTION: Your friend has three books. Book A is 20 cm wide, Book B is 18 cm wide, and Book C is 22 cm wide. If you want to put the widest book on a shelf that is 21 cm wide, will it fit? | ANSWER: Book C is the widest (22 cm). No, it will not fit on a 21 cm wide shelf because 22 cm is greater than 21 cm.

MCQ

Quick Quiz

Which of these objects is likely to be the widest?

A cricket stump

A railway track is designed to be much wider than a cricket stump, matchstick, or pencil to accommodate trains. The other options are very narrow objects.

Real World Connection

In the Real World

When you buy furniture for your home, like a wardrobe or a bed, you need to measure its width to make sure it fits through your door or in your room. Similarly, city planners measure the width of roads to ensure smooth traffic flow, especially in busy Indian cities, allowing buses and cars to pass easily.
