Using Boyle's Law (from the combined Ideal Gas Law), we find that the new volume is 1.409 liters. (See explanation)

Explanation:

We can solve this by using a variation of the Ideal Gas Law (PV = nRT). This variation is the combined Ideal Gas Law:

(P_1V_1)/T_1=(P_2V_2)/T_2P1V1T1=P2V2T2, which allows us to compare the changes made to pressure, volume, and temperature.

Since temperature is constant, T_1=T_2T1=T2, so our new comparison would be: (Boyle's Law)

P_1V_1=P_2V_2P1V1=P2V2

We need to find the new volume, V_2V2, so we rearrange the equation:
V_2=(P_1V_1)/P_2V2=P1V1P2

These are the values we have:
V_1=3V1=3 L
P_1=101P1=101 kPa
P_2=215P2=215 kPa

Plug in and solve:
V_2=V2= ((101 kPa)(3 L))/(215 kPa)=1.409 L(101kPa)(3L)215kPa=1.409L
