The Correct Answer and Explanation is:
Here are the correct answers:
Match the unit with the object:
- Kilometer: Distance to a church
- Meter: Length of a house
- Meter: Length of a calculator
- Meter: Height of a building
- Centimeter: Length of a bat
- Millimeter: Thickness of a dime
- Millimeter: Length of a worm
- Millimeter: Length of an ant
Write the measurement of the line segment in millimeters:
- 28 cm = 280 mm
- 657 mm
- 189 mm
Write the unit used to measure length:
- Length of an ant: Millimeter
- Height of a building: Meter
- Length of a calculator: Centimeter
- Length of a house: Meter
- Distance to a church: Kilometer
- Length of a worm: Millimeter
Explanation: The metric system is widely used for measuring length due to its consistency in unit conversions. The basic unit is the meter, with subdivisions and multiples including millimeters, centimeters, decimeters, decameters, hectometers, and kilometers. Each unit is a factor of ten apart, which makes conversions straightforward.
For small objects like worms and ants, the millimeter is the most appropriate unit since it represents one-thousandth of a meter. The centimeter, which is one-hundredth of a meter, is ideal for measuring moderately small objects such as bats or calculators. Larger structures such as houses or buildings require the meter, while the kilometer is used for long distances such as the space between locations.
Conversions between these units follow simple multiplication or division rules. For example, 28 cm equals 280 mm, since each centimeter is equivalent to 10 millimeters. The metric system’s decimal-based structure makes it highly efficient for scientific calculations and everyday measurements.
