Biocube29 water volume including LR & LS ???

[scuba-raru]

Question:

Does anyone know of a volume calculator that takes into account the water displaced by Live Rock & Sand in a tank?
The Deets:
I'm going to fill my BC29 using seawater (from LFS) but I'd like to take the right number of 5gal jugs to avoid multiple trips.
Tank Size 29 gallons
20lbs of LR
33lbs of LS (2" bed).
Any ideas on how many gallons of water I'll need to fill it? Thanks in advance!

You'll want your INTERNAL tank dimensions, including the sump section for best accuracy.
