Alternatively you could soak the sponge in a measuring tub of water, then hang it in a colander to drip off the water back into the tub. Honestly I think the volume will be off because the mass of water on the upper layer of the sponge will weight down on the bottom part and cause more water to drip off than it originally should.

It's hard to soak the water evenly inside the sponge through
Actually i think the best way to do it is measure the sponge in analytical scale (A). Then measure the weight of a cup full of liquid (full to very last drop) (B). Drop the sponge in, wait for it to sink. Clean all the water which surged out. Measure the weight of the cup with the sponge (C). Calculate volume:
V = (A+B-C)/(density of that liquid)
