I would guess 200 liters at most, to stay on the safe side.
If you want to know exactly, try to find a sales brochure or internet
description of your boat. With a bit of luck, it will state both the
total volume of your boat and the storage room. Total volume - storage =
cockpit volume.

My own pump uses a lead-acid battery, good for 25 minutes pumping. By
the way: TEST this, by installing the pump, filling the cockpit with
water, and start pumping while keeping the cockpit about half full.
Testing the pump out of the water will give no good indication of the
power usage.

My own 25 minutes of pumping will help me through 5 self rescues. That
should do for a normal trip.
