Sample practice questions
Easy
1. Convert 2.5 m to cm.
Answer: 250 — 1 m = 100 cm, so 2.5 m = 2.5 x 100 = 250 cm.
Easy
2. When converting an area from square metres to square centimetres, the conversion factor (100) must be:
Squared
Cubed
Used as-is (not squared or cubed)
Halved
Answer: Squared — Since area is two-dimensional, the linear conversion factor must be squared: 1 m^2 = (100cm)^2 = 10000 cm^2.
Medium
3. Convert 3 m2 to cm2.
Answer: 30000 — 1 m^2 = 10000 cm^2, so 3 m^2 = 3 x 10000 = 30000 cm^2.
