Sugar cubes

The glass has 600 ml of tea, which represents 80% of the volume of the glass. If you put twenty regular sugar cubes of 2 cm in the tea, how many ml of tea are poured?

Result

x =  10 ml

Solution:

V1=600 V=V1/0.80=600/0.80=750 V2=23=8 x=V1+20 V2V=600+20 8750=10 mlV_{1}=600 \ \\ V=V_{1} / 0.80=600 / 0.80=750 \ \\ V_{2}=2^{ 3 }=8 \ \\ x=V_{1} + 20 \cdot \ V_{2} - V=600 + 20 \cdot \ 8 - 750=10 \ \text{ml}
