    Full volume of a 20L cubie?

    Has anyone ever calculated or measured the actual volume of a 20L cubie when it is completely full with no air?

    I've been told that the 20L mark is actually the line at the top, leaving a bit of air, so I'm interested in knowing what the completely full volume is as I always fill mine right up.

    Previously I've guessed it to be about 22L, but it feels like that might be slightly under.

    I would say you're pretty close on the mark. The yellow cubbies are about 22 ltrs. The only thing I found is that they leak. Personally I much prefer the 25ltr square ones. They have a rubber seal in the lid.

    How's the shitbox prep going?

    Going pretty well thanks. I'm happy that the car is as mechanically sound as it can be. Had to put a new water pump in it, which wasn't ideal. Just took it on a family road trip from Sydney - Mudgee - Dubbo - Orange - Katoomba - Sydney and did 995 km fully loaded, using 64L of B100. I'm pretty happy with that as reasonable representation of what it might do on the rally as there were a couple of big hill climbs over the Divide in there with 2 adults & 2 kids + luggage and a full tank of juice when we started. As a factor of safety I've bumped the consumption estimate up from 6.4L/100 km to 7.0 and assumed my cubies are 20L full, rather than 22L.

    Carrying 13 x full cubies will be the challenge. It will fit but the suspension will hate it. If necessary, I plan to offer beer to other teams in exchange for transport of a 20L drum! Many hands make light work!

    3DB I heated a round bottom boiling flask in a pan of hot vegetable oil. During the experiment the oil overflowed on the hot heating element. Vegetable oil expands in volume as it gets hotter. So the exact volume of oil depends in part upon its' temperature.

    Bueff the yellow cubies will leak if you don't have the clear plastic seal which goes under the screw cap. Unfortunately most cooks chuck them away, so it is possible you have never seen one. I hang onto mine and have used And transported yellow cubies for over 10 years without problems. I don't fill them too full because if the container gets warm and you open it it will have a rather messy burp.
