100 cm is longer
990 cm is longer because 100 cm is one meter; that is 9.9 meters
1m = 100cm 1km = 1000m So .21km = .21 * 1000 * 100 = 21000 cm
The answer is 1 km.
There are 100 cm in a metre, and 1000 metres in a km, so that would be 100*1000, which gives you 100,000 cm in a km.
10 mm in 1 cm. 100 cm in 1 m. 1000m in 1km.
1km = 100 000cm
1km is 100 000cm
No
100 cm is longer
Well, honey, 10 meters is bigger than 1200 centimeters. Why? Because 10 meters is equal to 1000 centimeters, so it's a no-brainer. Don't let those pesky unit conversions trip you up!
There are 1000 meters per kilometer(km), and there are 100 cm per meter, so: 1km * 1000m/km * 100cm/m = 100,000 cm So, 1km= 100,000 cm
990 cm is longer because 100 cm is one meter; that is 9.9 meters
1 m = 100 cm 1 km = 1 000 m ⇒ 1km = 100 000 cm ⇒ 3 000 cm = 3 000 ÷ 100 000 cm = 0.03 km
Dimensional Analysis: (100 cm/1 meter)*(100 m/1km)=10,000cm/km
1m = 100cm 1km = 1000m So .21km = .21 * 1000 * 100 = 21000 cm
The answer is 1 km.
