Question

CHOOSING APPROPRIATE UNITS

Match each value with the most appropriate unit of measurement.

Column 1	Column 2
height of a sky scrapper: $2.6\times {10}^2$	inches
distance between two asteroids:$2.5\times {10}^5$	millimeter
depth of a bath tub:$1.6\times {10}^1$	miles
length of a memory chip:$7.8\times {10}^0$	meters

Answer 1

As skyscraper is very tall building which has multiple floors.So, its height should be in meters i.e. $2.6\times {10}^2$ meters.

As asteroids are very far from us , so distance between two asteroids should be in miles i.e. $2.5\times {10}^5$ miles.

As bathtub depths is small distance, so it should be in inches i.e. $1.6\times {10}^1$ inches.

As memory chip is very small , so length of a memory chip should be in millimeters i.e. $7.8\times {10}^0$ millimeters.
