How many centimeters are there in one kilometer?

• A. 1,000
• B. 10,000
• C. 100,000
• D. 1,000,000

Answer: (C)

One kilometer is defined as being equal to 1,000 meters. Since there are 100 centimeters in 1 meter, the total number of centimeters in a kilometer can be determined by multiplying the number of meters in a kilometer by the number of centimeters in a meter.

So, when you calculate it:

1 kilometer = 1,000 meters × 100 centimeters/meter = 100,000 centimeters.

This leads to the understanding that 100,000 is the correct amount of centimeters contained in one kilometer, confirming why this choice is accurate.
