Ubah lah satuan di bawah ini

Jawaban:

_ 1000 cm³ = ….10… m³

1 m = 100 cm

1000 cm = 1000/100 = 10 m

_ 2 kg = ….2000.000… mg

1 kg = 1000.000 mg

2 kg = 2 × 1000.000 = 2000.000 mg

_ 72 km/jam = …20… m/s

1 km = 1000 m

1 jam = 3600 sekon

maka :

72 km/jam = 72×1000/ 3600

72 km/jam = 72000/3600 = 20 m/s

1000cm^3=
1000/1.000.000
=1/1000
=0,001

2kg=
2×1.000.000
=2.000.000

72×1000=72000
60×60=3600
72000/3600=20m/s
