50+ Measuring in Centimeters worksheets for 3rd Class on Quizizz ... - Free Printable

Let's go through each question one by one and solve them with explanations.

1. What tool would you use to measure this real-life object?
*(Image: A stapler)*

- Options:
A) measuring cup
B) measuring tape
C) ruler
D) yardstick

✔ Correct Answer: C) ruler

Explanation:
A stapler is a small object, typically around 10–15 cm long. A ruler is the most appropriate tool for measuring small objects like this.
- Measuring cup → used for volume (liquids/solids), not length.
- Measuring tape → good for longer distances, but overkill for a small object.
- Yardstick → too large and not precise enough for small items.

So, ruler is best.

2. How long is the paper clip?
*(Image: Paper clip placed on a ruler from 0 to 3 cm)*

- Options:
A) 3 cm
B) 5 cm
C) 4 cm

✔ Correct Answer: A) 3 cm

Explanation:
The paper clip starts at 0 cm and ends at 3 cm on the ruler. So, its length is 3 cm.

3. How long is the black line?
*(Image: A black line on a ruler starting at 0 cm and ending just before 2 cm)*

- Options:
A) 2 cm
B) 7 cm
C) 10 cm
D) 1 cm

✔ Correct Answer: D) 1 cm

Explanation:
Looking closely, the black line starts at 0 and ends between 1 and 2 cm — but it appears to be about halfway or slightly less than 2 cm. However, if it’s clearly just past 1 cm, but not reaching 2 cm, and the options are whole numbers, we round to nearest cm.

But wait — let's re-express: If the line goes from 0 to just before 2 cm, and if it’s around 1.8 cm, then rounding to nearest cm would be 2 cm.

Wait — but in many such images, if the line ends at 1 cm, then it’s 1 cm.

But looking at your description: “starts at 0 and ends just before 2 cm” — that could mean ~1.8 cm, so rounded to nearest centimeter = 2 cm.

But option A is 2 cm, D is 1 cm.

However, if the line ends at the 1 cm mark, then it’s 1 cm.

Given the image shows the line ending before 2 cm, but likely at or near 1 cm, and since the answer choices are whole numbers, and the line appears to end at 1 cm, then:

✔ Correct Answer: D) 1 cm

Wait — but let's double-check:
If the line is from 0 to 1 cm, then it’s 1 cm.
If it's from 0 to 2 cm, it's 2 cm.

From your description: "ends just before 2 cm" — implies less than 2 cm, but possibly more than 1 cm.

But without seeing the exact image, based on typical quiz design, if it ends between 1 and 2, say at 1.5 cm, then nearest cm is 2 cm.

But here’s the key: The scale says:
```
1cm 2cm 3cm
```
And the black line extends from 0 to just past 1 cm?

Wait — actually, in standard versions of this type of question, the line often goes from 0 to 1 cm, so it's 1 cm.

But if it goes from 0 to 2 cm, it's 2 cm.

Let me assume the line ends at the 1 cm mark.

✔ Answer: D) 1 cm

But if it ends at 2 cm, then A) 2 cm.

Since you said “ends just before 2 cm”, it may not reach 2 cm. So maybe 1.5 cm, which rounds to 2 cm.

But again, without image, I’ll go with common version:
👉 Many similar quizzes show the line ending at 1 cm.

So D) 1 cm is likely correct.

But let’s suppose the line goes from 0 to 1.8 cm, then nearest cm is 2 cm.

Wait — the options include both.

But look: the ruler has markings every 1 cm, and the line ends just before 2 cm — so less than 2 cm, but more than 1 cm.

Then, if it’s 1.5 cm, it rounds to 2 cm.

So A) 2 cm might be correct.

This is ambiguous.

But in many such problems, if the line ends at 1 cm, it's 1 cm. If it ends at 2 cm, it's 2 cm.

But since it says “just before 2 cm”, it’s less than 2 cm, so could be 1.9 cm, which rounds to 2 cm.

So A) 2 cm is the best choice.

Wait — but the image might show it ending at 1 cm.

I think there's confusion.

Let me assume the image shows the line from 0 to 1 cm.

Then: ✔ D) 1 cm

But if it's from 0 to 2 cm, then ✔ A) 2 cm

Given the way it’s described: “the black line” on a ruler from 0 to 5 cm, and the line ends just before 2 cm, meaning not at 2 cm, so less than 2 cm.

So if it’s 1.7 cm, nearest cm is 2 cm.

Thus: ✔ A) 2 cm

Yes — because nearest centimeter:
- 1.5 cm → rounds to 2 cm
- 1.2 cm → rounds to 1 cm
- But if it's just before 2 cm, likely >1.5 cm → rounds to 2 cm

So ✔ A) 2 cm

Answer: A) 2 cm

4. Fill in the blank: The eraser is about ____ inches long.
*(Image: Eraser placed on a ruler from 0 to 2 inches)*

- Options:
A) 2 cm
B) 6 cm
C) 8 cm
D) 5 cm

Wait — the blank is in inches, but all options are in cm?

That’s odd.

But the question says: “The eraser is about ____ inches long.”
Then options are:
A) 2 cm
B) 6 cm
C) 8 cm
D) 5 cm

This is a problem — units don’t match.

But perhaps it's a typo. Or maybe the ruler is in inches, and they want the length in inches, but the options are in cm? That doesn't make sense.

Wait — maybe the eraser is measured in inches, and the answer should be in inches, but the options are labeled in cm? No.

Alternatively, maybe the ruler is in inches, and the eraser is about 2 inches long, but the options are in cm.

But then the correct answer would be about 5 cm, since 1 inch ≈ 2.54 cm → 2 inches ≈ 5.08 cm.

So if the eraser is 2 inches long, then it’s about 5 cm.

So the correct answer would be: ✔ D) 5 cm

Even though the blank says “inches”, but the options are in cm, likely the question meant to ask for the measurement in cm, or the blank is mislabeled.

But given the options, and the eraser appearing to be about 2 inches long (which is ~5 cm), then:

✔ Answer: D) 5 cm

5. What is the measurement of this line to the nearest centimeter?
*(Image: A line on a ruler from 0 to 10 cm, ending at about 7.5 cm)*

- Options:
A) 7 centimeters
B) 11 centimeters
C) 10 centimeters
D) 8 centimeters

The line starts at 0 and ends at 7.5 cm.

To the nearest centimeter:
- 7.5 cm → rounds up to 8 cm

So ✔ Answer: D) 8 centimeters

---

✔ Final Answers:

1. C) ruler
2. A) 3 cm
3. A) 2 cm *(assuming line ends just before 2 cm, e.g., 1.8 cm → rounds to 2 cm)*
4. D) 5 cm *(since 2 inches ≈ 5 cm)*
5. D) 8 centimeters

Let me know if you can describe the images more precisely (e.g., exact ruler markings), and I can refine further!
