tolong jawab semua pertanyaan ini

16) 18 m³/jam
= 18 × 1.000/3.600
= 5 liter/detik

17) vol = 20 liter = 20.000 cm³
waktu = 40 dtk
debit = vol ÷ waktu
= 20.000 ÷ 40
= 500 cm³/dtk

18) vol = 120 dm³ = 120 liter
waktu = 8 mnt = 8 × 60 = 480 dtk
debit = vol ÷ waktu
= 120 liter ÷ 480 dtk
= ¼ liter/dtk
= 0,25 liter/dtk

19) L = p × l
12dm² = 40 cm × l
1200 cm² = 40 cm × l
l = 1.200 ÷ 40
l = 30 cm
