tollong kerjain pakai cara

volume kolam renang
= p x l x t
= 12 m x 7 m x 2m
= 84m^2 x 2 m
= 168 m^3
= 1680 dm^3
= 1680 liter

debit
= liter/waktu
= 1680 liter/ 120 menit
= 168 liter / 12 menit
= 14 liter / menit

volume =
panjang×lebar×dalam
= 12×7×2
= 12×14
= 168 m³
= 1680 L

waktu =
2 × 60 menit
= 120 menit

debit = volume ÷ waktu
         = 1680 ÷120
         = 168 ÷12
         = 14 L/menit

smoga bermanfaat..
maaf kalo salah....
