Convert them into inches and add them all up.

$$15 cm \approx \frac{15cm}{2.5inches} \approx 6 inches$$
$$0.3 meters = 0.3 meters \times 100 \frac{cm}{meter} = 30 cm \approx 12 inches$$
Can you handle the rest?

Similarly, 1 meter = 100 cms. Then how many cms is 0.3 meters? It is 0.3*100 which is 30 cms. 
Now, convert the cms into inches.
1 inch = 2.5 cms. How many inches is 30 cms? 30/2.5 = 12inches.
