最上面果2個 抄問題@@ 咁咪姐係無答

1b.0.721cm3 = ?mm31cm3=10*10*10=1000mm30.721cm3=7210mm3寫錯左@@應該係721mm3 才對

1a. 1m = 100 cm
1m3 = 1000000 cm3
i.e. 3.04 m3 = 3040000 cm3

1b. 1 cm = 10 mm
1 cm3 = 1000 mm3
i.e. 0.721 cm3 = 721 mm3

1c. 1 km = 1000 m
1 km3 = 1000000000 m3
i.e. 0.00829 km3 = 8290000 m3

１ａ. 將3.04乘三次１００，因為１ｍ＝１００ｃｍ
１ｂ.0.721乘三次１０，１ｃｍ＝１ｍｍ
１ｃ.0.00829乘三次１０００，１ｋｍ＝１０００ｍ

1a) 3,040,000
我use moible phone 計ga~~
sorry!!

3.04m3 =304cm3
0.721cm3 =7.21mm3
0.008 29 km3 =8.29m3

1a.3.04m3 =?cm3

1b.0.721cm3 = ?mm3

1c.0.008 29 km3 =?m3


可以列步驟嗎!THX!!!
