Measuring a kumara

[Ocean]

Hi people,
How would you measure a kumara/sweet potato that is bigger than both your hands together? to get the volume of it. There are no measurements at all to go by

That's because you have an ordinary sweet potato. If you had a metric sweet potato, it would have a millimeter scale on it.

Find the volume by displacement of water. There are several ways to do this. One way is as follows:

Place the potato in a graduated cylinder large enough so the potato can be completely immersed in water. Carefully fill the cylinder with measured amounts of water until the potato is totally immersed and the water fills to a line over the potato. Record the amount of water needed to reach this line (let's use milliliters).

Empty the cylinder of the water and the potato.

Carefully refill the cylinder with measured amounts of water (with no spud) until the level reaches the same line as in the first step. Record this amount.

Subtract the amount of water with the potato from the amount of water alone. The answer is the volume of the potato in milliliters.

I am curious though, how would you measure the volume of the potato without water displacement if it fit in one hand?
