Question

How many centimeters are there in 1.23 x 10-6 kilometers?

Answer 1

1.23 x 10^6 = 1230000

from km to cm is adding 5 zeros so

123,000,000,000 cm or 1.23 x 10^11cm

Answer 2

The correct answer is 0.123 cm.

Explanation:

Each kilometer has 1000 meters and each meter has 100 centimeters.

Hence each kilometer has 1000×100=100000=105 centimeters.

Therefore, 1.23×10−6 kilometer will have

1.23×10−6×105=1.23×10−6+5=1.23×10−1 or 0.123 centimeters
