Measuring Capacity- Littres worksheet - Free Printable

Let's solve the problem step by step.

We are given 8 graduated cylinders, each marked in milliliters (ml), and we need to read the volume of liquid in each one. The key is to look at the bottom of the meniscus (the curved surface of the liquid) and read the measurement at eye level.

Each cylinder has markings from 0 to 25 ml, with major lines every 5 ml and smaller lines between them (each small line = 1 ml).

Step-by-step readings:

#### 1. First cylinder:
- The liquid reaches just above 20 ml, but not quite at 21.
- The top of the liquid is at 21 ml? Wait — let’s check carefully.
- Actually, looking closely: the liquid level is at the 20 ml mark.
- ✔ Reading: 20 ml

#### 2. Second cylinder:
- Liquid is just below 10 ml.
- It's halfway between 5 and 10 → so 7.5 ml?
- But wait — look again. The markings: from 5 to 10, there are 5 small lines → each is 1 ml.
- The liquid is at the 6th line after 5, which is 6 ml?
- No — wait: if it's at the first line above 5, that's 6 ml.
- But actually, the liquid is at the top of the 6th line? Let's count:
- From bottom: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10...
- The liquid is at the 8th line from the bottom? Wait — no.
- The scale goes: 5, then small lines for 6, 7, 8, 9, 10.
- The liquid is at the 8th line — that would be 8 ml.
- Wait — no, let's re-check: the liquid is clearly between 5 and 10, and it's at the third line above 5 → 5 + 3 = 8 ml.
- ✔ Reading: 8 ml

Wait — I think I'm overcomplicating. Let's go more systematically.

Actually, all cylinders have major ticks at 5, 10, 15, 20, 25.
Between each 5 ml interval, there are 5 small divisions, so each small division = 1 ml.

So:

---

1. Cylinder 1:

- Liquid is exactly at 20 ml
- ✔ 20 ml

2. Cylinder 2:

- Liquid is between 5 and 10, and it's at the second small line above 5 → 5 + 2 = 7 ml
- Wait — no: if 5 is marked, then next line is 6, then 7, etc.
- The liquid is at the 7 ml mark? Let's see: from 5 to 10: five lines → 5, 6, 7, 8, 9, 10.
- The liquid is at the 7 ml line → yes.
- But wait — the image shows the liquid level just below 10, but clearly at 8 ml? Let me double-check.

Looking at the image:
- In cylinder 2, the liquid is at the third line above 5, so:
- 5, then 6, 7, 8 → so 8 ml
- ✔ 8 ml

Wait — let’s be precise.

Actually, upon close inspection:
- Cylinder 2: the liquid is at the 8 ml mark → because it's two lines above 6? No.
- Better: from 5 to 10, there are 5 spaces → each space = 1 ml.
- The liquid is at the third tick above 5 → 5 + 3 = 8 ml
- ✔ 8 ml

But wait — some people might misread. Let’s confirm.

Actually, let's do all eight carefully.

Final Readings:

#### 1. Cylinder 1:
- Liquid is at the 20 ml line
- ✔ 20 ml

#### 2. Cylinder 2:
- Liquid is at the 8 ml line (3 lines above 5)
- ✔ 8 ml

#### 3. Cylinder 3:
- Liquid is at the 10 ml line
- ✔ 10 ml

#### 4. Cylinder 4:
- Liquid is at the 12 ml line?
- Let's see: 10, then 11, 12... yes, the liquid is at the second line above 10 → 10 + 2 = 12 ml
- ✔ 12 ml

#### 5. Cylinder 5:
- Liquid is at the 17 ml line
- Because it's at the second line above 15 → 15 + 2 = 17 ml
- ✔ 17 ml

#### 6. Cylinder 6:
- Liquid is at the 16 ml line
- At the first line above 15 → 15 + 1 = 16 ml
- ✔ 16 ml

#### 7. Cylinder 7:
- Liquid is at the 4 ml line
- Just below 5, at the fourth line from 0 → 0, 1, 2, 3, 4 → so 4 ml
- ✔ 4 ml

#### 8. Cylinder 8:
- Liquid is at the 14 ml line
- Between 10 and 15: at the fourth line above 10 → 10 + 4 = 14 ml
- ✔ 14 ml

Explanation:

To measure capacity using a graduated cylinder:
- Always read the bottom of the meniscus (the curved surface of the liquid).
- Ensure your eyes are level with the liquid surface to avoid parallax error.
- Each large marking is 5 ml, and each small marking is 1 ml.
- Count the small lines from the nearest lower number to get the exact reading.

These values are based on careful observation of the liquid levels in each cylinder.
