To solve the problem of estimating the capacity of each item, we need to consider the typical sizes and uses of these objects. Let's go through each item and select the most sensible estimate for its capacity.
1. Watering Can
-
Options: 4 ml, 4 litres, 40 ml
-
Reasoning: A watering can is designed to hold a significant amount of water to water plants. It is much larger than a few millilitres but not as large as a bathtub.

Reasoning: A bath is a large container used for bathing, which requires a substantial volume of water. It is much larger than a litre or 150 ml.
-
Answer: 150 litres
3. Cereal Bowl
-
Options: 500 ml, 10 ml, 5 litres
-
Reasoning: A cereal bowl is used for serving food and typically holds a moderate amount of liquid or food. It is much larger than 10 ml but not as large as 5 litres.
-
Answer: 500 ml
4. Can of Soup
-
Options: 20 ml, 400 ml, 1 litre
-
Reasoning: A can of soup is a standard size that typically holds a portion of soup. It is much larger than 20 ml but not as large as 1 litre.
-
Answer: 400 ml
5. Mug
-
Options: 20 ml, 250 ml, 2 litres
-
Reasoning: A mug is used for drinking beverages and typically holds a moderate amount of liquid. It is much larger than 20 ml but not as large as 2 litres.
-
Answer: 250 ml
6. Teaspoon
-
Options: 250 ml, 50 ml, 5 ml
-
Reasoning: A teaspoon is a small measuring tool used for very small amounts of liquid or powder. It is much smaller than 250 ml or 50 ml.
-
Answer: 5 ml
7. Kettle
-
Options: 2 ml, 2 litres, 20 litres
-
Reasoning: A kettle is used for boiling water and typically holds a moderate amount of water. It is much larger than 2 ml but not as large as 20 litres.
-
Answer: 2 litres
8. Swimming Pool
-
Options: 4 litres, 400 litres, 400,000 litres
-
Reasoning: A swimming pool is a very large container used for swimming and requires a massive volume of water. It is much larger than 4 litres or 400 litres.
-
Answer: 400,000 litres
