📝 Explanation:
To measure:
1. Align the
left end of the object with
0 cm on the ruler.
2. Look at where the
right end of the object lines up.
3. Estimate the position between the centimeter marks.
4. Round to the
nearest whole number — if it's halfway or more, round up; otherwise, round down.
For example:
- 3.2 cm → rounds to
3 cm
- 14.3 cm → rounds to
14 cm
- 8.4 cm → rounds to
8 cm
- 6.3 cm → rounds to
6 cm
