I know this has already been determined by manufacturer specs. but I just wanted to add another way to figure out the volume of a tank with less math and less chance of error. I usually mark the waterline before a WC. I use a piece of tape. Then remove a determined amount, for me 10 gallons, and measure the difference. Divide the overall height with the figure of the amount removed and you have the volume. Works well for bow tanks.
