The formula to calculate the antifreeze volume (AV) is:
\[ AV = \left(\frac{AP}{100}\right) \times TV \]
Where:
Let's say the antifreeze percentage (AP) is 50% and the total coolant volume (TV) is 10 gallons. Using the formula:
\[ AV = \left(\frac{50}{100}\right) \times 10 = 5 \]
So, the antifreeze volume is 5 gallons.
