means A unit of volume equal to the space inside a cube measuring one foot on each edge — 1,728 cubic inches of whatever you're measuring, air included.
from Straightforward compound arithmetic, not myth: 'cubic' comes from Latin cubus, borrowed from Greek kybos meaning 'die' (as in dice) or cube-shaped block, and 'foot' is the old body-based unit of length, originally just the length of an actual human foot before it got standardized. Put them together and you get exactly what it says — a foot-cube. The unit became essential with the rise of standardized trade, construction, and shipping, where everyone needed to agree on how much space a 'foot' of lumber, water, or gas actually took up.
