No I didn't measure it to see exactly, I have another empty though, so i will try to do that for ya.
What I did to clean it, OUr water heater it turned up a bit, so it;s really hot our of our tap "g/f likes really hot water in her shower"
I just filled it with Hot water out of the Tap after I did a hot water rinse "this was a few cups at least, swiched around and dumped out" to get the loose stuff first,
Then filled it to the rim, put the lid on and let it set untell the next day sometime.
After the water was cold, dumped it, rinsed once more with hot water to worm the jug up,
then used a towl and about 5 minutes time to scrub off any let oily spots. then is was
nice n spitty clean, filled it with a couple cups of gravle out of one tank, then half full of the same water, then filled with tap water rest of the way n delored it.
Then got a little box filter, fixed it u, n air pump, let it run for a day, then added 4 tiny gups, just added one more last night "was in a fry tank, it was real fat and thgought it was going to have fry, but didn;t for some reaosn...
Added the wood n plant a couple days later and skippies,, ther ya have it.........
I do wanna use a few of the pork rine ones for betta's later on......but that'll be awhile, I don;t like um that much to eat them tubs full "shorter then the cheese balls if you didn;t know......
