4.5 liters (1.2 gallons)

|
3.5 liters (.9 gallons)

Explanation:
Detailed explanation-1: -Answer: In gallons, the average total lung capacity is 1.56 gal. Q. What is the total lung capacity in human beings?
Detailed explanation-2: -Total Lung Capacity(TLC) It is the maximum volume of air the lungs can accommodate or sum of all volume compartments or volume of air in lungs after maximum inspiration. The normal value is about 6, 000mL(4‐6 L).
Detailed explanation-3: -Normal findings of spirometry are an FEV1/FVC ratio of greater than 0.70 and both FEV1 and FVC above 80% of the predicted value. If lung volumes are performed, TLC above 80% of the predictive value is normal. Diffusion capacity above 75% of the predicted value is also considered normal.
