Tolong Yah Kakak yang Baik...baik

  0,5 [tex] m^{3} [/tex] - (150 [tex]dm^{3} [/tex] + 110 [tex]dm^{3} [/tex] + 180 [tex]dm^{3} [/tex]
=500 liter - (150 liter + 110 liter + 180 liter)
=500 liter - 440 liter
=60 liter (A)
Semoga membantu :) :) :)

0,5 m³ = 500 dm³
500 dm³ - (150dm³ + 110 dm³ + 180 dm³)
= 500 - 440
= 60 liter.
