Let’s solve each problem step by step.
We are measuring the length of each object using a ruler marked in centimeters (cm). The key is to see where the
left end of the object lines up with the ruler, and then read the number at the
right end.
But — look carefully! In all these problems, the left end of each object starts at
0 cm. That makes it easy: we just read the number on the ruler that matches the right end of the object.

1) Eraser
Left end: 0 cm
Right end: lines up with
6 cm
→ Length = 6 cm
---
2) Pencil sharpener
Left end: 0 cm
Right end: lines up with
4 cm
→ Length = 4 cm
---
3) Marker
Left end: 0 cm
Right end: lines up with
12 cm
→ Length = 12 cm
*(Note: The cap sticks out a little, but we measure from tip to end of body — yes, it goes to 12.)*

4) Crayon
Left end: 0 cm
Right end: lines up with
8 cm
→ Length = 8 cm
---
5) Paintbrush
Left end: 0 cm
Right end: lines up with
10 cm
→ Length = 10 cm
---
All measurements start at 0, so no subtraction needed. Just read the endpoint.
Final Answer:
1) 6
2) 4
3) 12
4) 8
5) 10
