L=150s*500 ml=75000ml = ( 75000ml÷1000ml)= 75 litri apa
M=250s*500ml=125000ml=(125000ml÷1000ml)=125 litri apa
M=200s*500ml=100000ml=(100000ml÷1000ml)=100 litri apa
J=300s*500ml=150000ml=(150000ml÷1000ml)=150 litri apa
V=250s*500ml=125000ml=(125000ml÷1000ml)=125 litri apa
75 l + 125 l + 100 l +150 l + 125 l =575 l
