Answer
a) Metres should be used because the height of a building is a linear measure less than a kilometer.b) Grams should be used because the mass of a pen is less than a kilogram.c) Litres should be used because the capacity of a paddling pool is more than a litre.
Explanation
## Step 1: Understanding the problemThe problem involves the selection of the appropriate unit of measurement for different quantities. The available options are different for each quantity.## Step 2: Selecting the unit for the height of a buildingWe need to consider the typical height of buildings. Buildings are generally not measured in centimeters because they are too tall for such a small unit. Similarly, buildings are not usually measured in kilometers because they are not tall enough to reach such a large unit. The most appropriate unit of measurement for the height of buildings is meters. This is because buildings are typically measured in meters, which is a unit that is neither too small nor too large for the height of a building.## Step 3: Selecting the unit for the mass of a penThe mass of a pen is typically very small. Therefore, tonnes, which is a very large unit, would not be appropriate. Kilograms could be used, but it would result in a very small number, which could be inconvenient. Therefore, the most appropriate unit to use for the mass of a pen would be grams.## Step 4: Selecting the unit for the capacity of a paddling poolThe capacity of a paddling pool is typically quite large, so milliliters, which is a very small unit, would not be appropriate. Therefore, the most appropriate unit to use for the capacity of a paddling pool would be litres.
