You can't.
1. the picture does not show a circuit.
2. the picture does not show the two points that the resistance is to be taken between.
3. there appears to be a short-circuit between the left and right-most extreme nodes.

Once the above issues are sorted out - you will find the total resistance by simplifying the circuit. It can help to redraw it.

Thank you for the scrutiny. Is this satisfactory now? I am sorry I there are still errors to tend to in the diagram, I hope I was able to convey enough information this time

Total resistance between nodes A and B

I don't see any symmetry that would help you out here so it seems to me you'll just have to do a ton of delta-Y transforms and simplify the circuit bit by bit. Looks to conceptually trivial but VERY messy to actually carry out.

I suggest a box of assorted precision-resistors and a good ohmmeter.

I'm tempted to say "about 2 ohms".

There is a 1 and a 2 "in series" between a and b with mostly higher values "in parallel".

If you model it as a 1+2 in parallel with a 3+4+5 you get about 2.4 Ohms.
