0.000003
0.00003
0.0003
0.003
A 2-column table with 7 rows. Column 1 has entries kilo, hecto, deka, unit, deci, centi, milli. Column 2 has entries 1,000, 100, 10, 1, 0.1, 0.01, 0.001.

Answer 1

To convert centimeters to kilometers, we need to know the conversion factors:

1 kilometer = 1,000 meters
1 meter = 100 centimeters

Putting it together, we can express 1 kilometer in terms of centimeters:
1 kilometer = 1,000 meters × 100 centimeters/meter = 100,000 centimeters

Now, to convert 3 centimeters to kilometers, we use the following conversion factor:

\[
\text{Kilometers} = \text{Centimeters} \times \left(\frac{1 \text{ kilometer}}{100,000 \text{ centimeters}}\right)
\]

Calculating this gives:

\[
3 \text{ cm} \times \left(\frac{1 \text{ km}}{100,000 \text{ cm}}\right) = \frac{3}{100,000} \text{ km} = 0.00003 \text{ km}
\]

Thus, the answer is: **0.00003 kilometers**.
