What units in the metric system would you use to measure each of the following
quantities?
(a) Distance from Los Angeles to New York
(b) Your waist measurement
(c) Width of a hair
(d) Your height
a km
b cm
c mm
d cm or m
(a) Distance from Los Angeles to New York: Kilometers (km) or meters (m) can be used to measure this distance.
(b) Your waist measurement: Centimeters (cm) or meters (m) can be used to measure this measurement.
(c) Width of a hair: Micrometers (µm) can be used to measure this very small width.
(d) Your height: Meters (m) or centimeters (cm) can be used to measure this measurement.
To measure each quantity using units in the metric system, you would use the following:
(a) Distance from Los Angeles to New York:
For large distances like the distance between cities, you would typically use kilometers (km) in the metric system. To measure the distance from Los Angeles to New York, you can refer to a map or use a mapping application to find the straight line distance or the driving distance.
(b) Your waist measurement:
For measuring personal body measurements, including waist circumference, you would use centimeters (cm) or meters (m) in the metric system. To measure your waist, you can use a flexible tape measure and wrap it around your waist, making sure it's snug but not too tight.
(c) Width of a hair:
Since the width of a hair is very tiny, you would use millimeters (mm) or even micrometers (μm) in the metric system to measure it accurately. A common way to estimate the width of a hair is to compare it with an object of known size, such as the width of a paperclip or a grain of rice.
(d) Your height:
For measuring height, you would typically use meters (m) or centimeters (cm) in the metric system. You can measure your height using a measuring tape or a stadiometer mounted on a wall. Stand up straight against the wall and have someone measure from the floor to the top of your head. This measurement will give you your height in centimeters, and you can convert it to meters if needed.
