Question

1. how many centimeters are in 1 kilometer?

100 km
100,000 cm
1,000 cm
100 cm

Explanation:

Step1: Recall unit conversions

We know that \(1\) kilometer \(= 1000\) meters and \(1\) meter \(= 100\) centimeters.

Step2: Convert kilometers to centimeters

To find the number of centimeters in \(1\) kilometer, we first convert kilometers to meters and then meters to centimeters.
Since \(1\) km \( = 1000\) m and \(1\) m \( = 100\) cm, we multiply the number of meters in a kilometer by the number of centimeters in a meter: \(1000\times100 = 100000\) cm.

Answer:

100,000 cm (the option corresponding to this value)
