3 metres is bigger.
2000 dm is the same as 200 m. 2000 dm is longer than 20 m, not bigger.
3 m = 300 cm which makes it bigger than 200 cm
200 dm
dm = decameter 1 dm = 10 m answer: 50 dm
No
500 m
30dm = 300cm = 3m. They're the same.
0.85 m
10 m = 100 dm 100 dm > 78 dm 10 m > 78 dm
There are 1,000 dm³ in 1 m³. Therefore, to convert 0.2 m³ to dm³, you multiply by 1,000. This means 0.2 m³ is equal to 200 dm³.
10 dm = 1 m so 200 dm = 200/10 = 20 metres. Simple!
They are equivalent.
