5 liters.

Explanation:

We are being given the expression

V = 0.041h - 0.018A - 2.69

The height h is 165 cm.

The Age A is 65 years old.

So we replace the values of h and A in the equation given:

V = 0.041 * 165 + 0.018 * 65 - 2.69 = 5.245 liters.

Rounding, we notice that 5.245 liters is closer to 5 than 6. So the answer would be 5 liters.
