To calculate the amount of apple juice left in the batch, we'll subtract the quantity removed for quality testing from the initial batch size.
The initial batch size is given as 0.07 m³, which is equivalent to 70,000 cm³ (since 1 m³ = 1,000,000 cm³).
The quantity removed for quality testing is given as 2000 cm³.
Therefore, to find the remaining apple juice, we'll subtract 2000 cm³ from 70,000 cm³:
70,000 cm³ - 2000 cm³ = 68,000 cm³
So, there are 68,000 cm³ of apple juice left in the batch.
