點解
1平方公里等於1000000平方米?
1平方米等於10000平方厘米?
1平方厘米等於100平方毫米?
1立方米等於1000升?

有冇人可以話比我知其實係點轉架?

✔ 最佳答案
1 km^2
= 1 km x 1 km
= 1000 m x 1000 m
= 1000000 m^2

1 m^2
= 1 m x 1 m
= 100 cm x 100 cm
= 10000 cm^2

1 cm^2
= 1 cm x 1 cm
= 10 mm x 10 mm
= 100 mm^2

1 m^3
= 1 m x 1 m x 1 m
= 100 cm x 100 cm x 100 cm
= 1000000 cm^3
= 1000000 mL
= 1000 L
