Right we're comparing the relationship of lengths and volumes. Volume is three-dimensional, so we multiply:

(volume of small bottle)*[(ratio of lengths)^(dimension of volume)]

480 * (30/20)^3 = 480 * (27/8) = 60*27 = 1620ml
How about when the bottles are 15cm and 21cm and the smaller bottle can hold 500ml of water How much can the other bottle hold
