1 dm = 1 cm → 1 dm² = 1 dm × 1 dm = 10 cm × 10 cm = 100 cm² → To convert dm² to cm² multiply by 100 → 5 dm² = 5 × 100 cm² = 500 cm².
2 dm
240 cm
1 cm is equal to 10 dm
10 cm = 1dm ⇒ 150 cm = 150 ÷ 10 dm = 15 dm
A cm is ten times smaller than a dm
40 dm is equal to 400 cm, as there are 10 cm in 1 dm.
there are 10 cm to a dm, meaning 1000 cm = 100 dm.

The volume of the box in cubic centimeters is 5000 cm³ (25 cm * 2 dm * 1 dm * 10 cm/dm). The volume of the box in cubic decimeters is 10 dm³ (0.25 dm * 0.2 dm * 0.1 dm * 1000 cm³/dm³).
By unit of length and distance and conversion ,we can say that 1 dm =10 cm 2 dm=20 cm hence ,2 dm >18 cm
10 cm = 1 dm 20 cm = 2 dm
