2.5 dm
since 1 dm is 10 cm, there are 25 cm in 2.5 dm.
1 dm = 10 cm 200 dm = 2000 cm
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).
10 cm in 1 dm
The centi- prefix means one hundredth → 1 cm = 0.01 cm The deci- prefix means one tenth → 1 dm = 0.1 cm → 25 cm : 9 dm = 25 × 0.01 m : 9 × 0.1 m = 0.25 m : 0.9 m = 0.25 : 0.9 = 25 : 90 The radio of 25cm to 9 dm is 25:90
there are 200 cm in 20 dm
1 dm = 10 cmSo 5 cm = 0.5 dm
1,000,000 cm = 100,000 dm
10 cm = 1 dm so 2.7 cm = 2.7/10 = 0.27 dm. Simple!
10 cm = 1 dm so 145 cm = 145/10 = 14.5 dm. Simple!
0.125 dm
