Let's see how you got on:
- How many square millimetres are there in a square centimetre?
1 cm = 10 mm, so 1 cm2 = 10 × 10 = 100 mm2.
- How many square centimetres are there in a square metre?
1 m = 100 cm, so 1 m2 = 100 × 100 = 10,000 cm2.
- How many square metres are there in a square centimetre?
1 cm = 0·01 m, so 1 cm2 = 0·01 × 0·01 = 0·0001 cm2. |
The last one was tricky, but not impossible - once you know how!
