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
To determine the numeric value of volume on the given graph, you need to refer to the scale provided on the horizontal axis. The graph states that the vertical divisions represent 2.00 * 10^-3 m^3. This means that each division on the horizontal axis corresponds to a volume change of 2.00 * 10^-3 m^3.
To find the volume at a specific point on the graph, count the number of divisions from the reference point (usually the origin) to the desired point and multiply it by the corresponding volume change per division.
For example, if a point is two divisions away from the reference point, the corresponding volume would be:
Volume = 2 divisions * 2.00 * 10^-3 m^3/division
Once you determine the volume for each segment of the path (A to B, B to C, and C to A), you can proceed to calculate the work done in each segment.
