(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Given the cycle shown below, what is the total work done by the gas in the cycle?

2. Relevant equations

ΔU = ΔQ + ΔW

W = PΔV

3. The attempt at a solution

W = 0

W = PΔV = 2 x (6-1) = 10

W = (1/2)bh = (1/2) (5-2) (6-1) = 7.5

W = W + W + W = 0 + 10 + 7.5 = 17.5

Since the volume is increasing, Work is positive.

It says I am wrong. So any help would be appreciated. I think I might know the issue, but want feedback.
