Let's solve this step by step. The task is to choose the correct unit of measurement—either
centimeters (cm) or
meters (m)—for each given object based on its size. We are reminded that:
>
1 meter = 100 centimeters
We'll go through each item and determine whether the measurement makes more sense in
cm or
m.

1. Length of a carrot: 32 ___
- A typical carrot is about the length of a hand.
- It’s much shorter than a meter.
- 32 cm is reasonable (about 1 foot).
-
Answer: cm
---
2. Height of a shaker: 8 ___
- A salt shaker is small, usually around the height of a cup.
- 8 meters would be huge (like a tall building), so that can't be right.
- 8 cm is about the size of a small bottle.
-
Answer: cm
---
3. Length of a dump truck: 11 ___
- A dump truck is a large vehicle, typically over 10 meters long.
- 11 cm would be smaller than a pencil.
- So, 11 meters is realistic.
-
Answer: m
---
4. Length of a swimming pool: 40 ___
- Swimming pools are long—often 25 to 50 meters.
- 40 cm is just 16 inches—way too short.
- So, 40 meters is reasonable.
-
Answer: m
---
5. Length of a shovel: 1 ___
- A shovel is longer than a meter? Not really.
- A typical shovel handle is about 1 meter long.
- But let’s think: 1 cm is only about the width of your pinky—too small.
- So, 1 meter makes sense.
-
Answer: m
---
6. Width of a house: 15 ___
- Houses are wide—typically 10 to 20 meters across.
- 15 cm is about the width of a book—too narrow.
- 15 meters is reasonable for a house width.
-
Answer: m
---
