C

D

Solution

The correct option is C 300000 cm

We know that 1km = 1000m

Therefore 3 km = 3 × 1000 m

= 3000 m

Now we know that 1m = 100 cm

Therefore 3000 m = 3000 × 100 cm

= 300000 cm

So, Raju covered 300000 cm in a day.

Method 2

We can also solve this problem using a measurement table.

Looking at the table

When we convert a larger unit (km) to a smaller unit (m) we multiply by the conversion factor.

Therefore to convert 3 km to meters we have to multiply 1000

I.e. 3km = 3 x 1000 m = 3000 m

Now again to convert 3000 m to cm we have to multiply by 100

3000 m = 3000 × 100 cm = 300000 cm

Answer = 300000 cm.
