## Question

Write five units of measurement of each length, area and volume.

## Short answer

Length units include millimetre, centimetre, metre, kilometre, and foot. Area units are square millimetre, square centimetre, square metre, hectare, and ropani. Volume units are cubic millimetre, cubic centimetre, cubic metre, litre, and cubic foot.

## Answer

| Dimension | Five units |
|---|---|
| Length | millimetre (mm), centimetre (cm), metre (m), kilometre (km), running metre (rm), foot (ft), inch (in), yard |
| Area | square millimetre (mm²), square centimetre (cm²), square metre (m²), hectare (ha), square foot (ft²), ropani, aana (Nepali land units) |
| Volume | cubic millimetre (mm³), cubic centimetre (cm³), cubic metre (m³), litre (L), cubic foot (ft³), cubic yard |

Standard SI units used in estimating are m, m² and m³. Useful conversions: 1 m = 3.281 ft, 1 m² = 10.764 ft², 1 m³ = 35.315 ft³ = 1000 L, 1 ropani = 508.72 m².

## Check yourself

3. A ropani is about
   A. 50.87 m²
   B. 5087 m²
   C. 508.72 m²
   D. 10.76 m²
   Answer: C. 1 ropani = 508.72 m². (Key point: Nepali area unit)
