How many square centimetres (cm2) are 12 square metres (m2)?
Answer and explanation
Correct answer: C. 120000 cm2
- Step 1: 1 m2 = 100 cm x 100 cm = 10,000 cm2. Step 2. 12 x 10,000 = 120000 cm2. Answer: 120000 cm2. Why not the others: 1200 cm2: 1 m2 was treated as 100 cm2. 12000 cm2: 1 m2 was treated as 1,000 cm2. 1200000 cm2: an extra factor of 10 was applied.
