Let’s solve this step by step.
We are measuring each object to the
nearest centimeter (cm) using the ruler shown below each object. The rulers go from 0 to 10 cm, and we look at where the object ends — then round to the nearest whole number.

1. Candy (red with brown wrappers):
- The left end of the candy is lined up with 0 cm.
- The right end goes just past 2 cm — it looks like about 2.3 or 2.4 cm.
- To the nearest cm → that’s
2 cm.
✔ Check: Since it’s less than halfway to 3 cm (which would be 2.5), we round down.

2. Glasses:
- Left end at 0 cm.
- Right end goes a little past 4 cm — maybe 4.2 or 4.3 cm.
- Nearest cm →
4 cm.
✔ Check: Less than 4.5, so rounds down.

3. Pencil:
- Left end at 0 cm.
- Right end (tip) goes almost to 9 cm — looks like about 8.8 or 8.9 cm.
- Nearest cm →
9 cm.
✔ Check: Very close to 9, definitely over 8.5 → rounds up.

4. Key:
- Left end at 0 cm.
- Right end (the bow part) goes to about 3.2 or 3.3 cm.
- Nearest cm →
3 cm.
✔ Check: Under 3.5 → rounds down.

Final Answer:
Candy: 2 cm
Glasses: 4 cm
Pencil: 9 cm
Key: 3 cm
