Younger gives several heights of pots with associated volumes. The smallest listed with height is 40.6 liter at 48 cm high. If the height increases by a factor of 3.542 to 170 cm, the volume should increase by a factor of the cube of 3.542, or 44.438, which would be 1804 liter. The capacity of the 170 cm pot, however, is 996, half the amount estimated using the cube, and that is generally true of the several pots for which Younger lists heights. An exponent of 2.53 estimates the increase in capacity, which means that, at least for these vases, the potters did not add to the diameter to keep the same proportion between diameter and height; the larger vases were made thinner.
