It appears that the reading has been made at constant pressure.
At constant pressure, the gas law formula is
V/T = constant V is volume and T is temperature of the gas.
V₁ / T₁ = V₂ / T₂
V₁ = 6.6 L,
T₁ = 40°C
= 273 + 40
= 313 K
T₂ = 15 + 273
V₂ = ?
Putting the values in the formula above
6.6 / 313 = V₂ / 288
V₂ = 6.07 L.
