Question

Convert into indicated units:

(i) 10 l and 50 ml into ml

(ii) 4 km 3 m 25 cm into cm

Answer 1

(i) 1 litre = 1000 ml

10 litre = 10000 ml

Here, 10 l 50 ml = 10000 ml + 50 ml = 10050 ml

(ii) 4 km 3 m 25 cm into cm

[ $\because$ 1 km = 1000 m 1 m = 100 cm ]

4 km = 400000 cm

3 m = 300 cm

4 km 3 m 25 cm = 400000 cm + 300 cm + 25 cm

= 400325 cm
