Answer 1

Answer:

8.5 cm

Step-by-step explanation:

Concept used:

1 cm is equal to 10 mm

→ 1 mm = 0.1 cm

Solution:

The length of pencil has been given to us as 8 cm 5 mm.

We need to express this length in cms.

1 mm = 0.1 cm

Similarly, 5 mm = 5 × 0.1 = 0.5 cm

So, The total length = 8 cm + 0.5 cm

⇒ Length = 8.5 cm

∴ Total length of the pencil in cm = 8.5 cm
