If you take your 69 gallons x 834 lbs/gal for water, you get 57546 lbs (if your rock were water it would weigh this much) Since it's rock and weighs 1645 lbs, you divide it's 1645 lb weight by the weight of the water it displaces, 57546 lbs, and you get a SPECIFIC GRAVITY of 28586, meaning your rock is 28586 times more dense than water
