The pressure and volume of a gas are changed along a path ABCA in the figure. The vertical divisions on the graph represent 3.50 105 Pa, and the horizontal divisions represent 2.00 10-3 m3. Determine the work done (including algebraic sign) in each segment of the path.

This problem gives me a pressure versus volume plt graph to read. how do i tell the volvume. i can understand the positive and negative of the graph,but i can't tell the numeric value for the different volumes
