Best Answer

The key to this is in the prefix that is used. The main ones that you hear are

1). deci- means a tenth of

2). centi- means one hundredth of

3). mili- means one thousandth of

so a centimeter is a hundredth of a meter.

so 300 hundredths is the same as 3 units, just as 300 centimeters is the same as 3 meters.

another example 30 decimeters is the same as 3 meters, the key is regconising that 30 tenths is the same as 3 units.

3 meters = 300 centimeters

Each decimeter is 10 cm. 300 cm = 30 dm.

3 metres = 300 centermetres (cm)

1 m is equivalent to 100 cm. So, 3m = (3 x 100) cm = 300 cm 3 m 67 cm = 300 cm + 67 cm = 367 cm.
