The socially efficient quantity is where the sum of private value and external benefit equals private cost. At quantity 3, private value (18) + external benefit (10) = private cost (18). The total surplus is the sum of (private value + external benefit - private cost) for quantities 1 to 3: (22+10-12) + (20+10-15) + (18+10-18) = 10 + 15 + 10 = 35.
