    My best estimate would be
    3 1/2x 91/2 =33.25 Cubic Inches = 18.42 Fluid Ounces
    I don't think it's square.

    6.5 cups.
    Hmm, I think you're right. I was going to say 7 cups, but after recalculating, 6.5 is correct.
    I got 34.87. Crap. Can you guys show me your work?

    d = 3.5 in
    r = 1.75 in
    h = 9.5 in
    A = pi*r^2 = 9.62in^2
    V = A*h = 91.39in^3

    91.39 cubic inches is equal to 50.64 US fl oz
    That equals 6 1/3 cups.

    But really, just take a measuring cup and fill it.

    step on the scale.
    Drink the full bottle of water
    step back on the scale.
    Take the weight difference.

    then using your current altitude, the outside air pressure, and the density of the last crap that you took you can calculate the exact volume of water that you consumed.

    If you haven't been tracking your crap density then I just can't help you if you won't help yourself.

    It's possible. But one generally thinks of bottles as round, so surely she would have specified.

    Assuming it's not a thick-walled or double-walled container and that it's a reasonably-regular cylinder, you can get the volume with the simple formula of

    Volume = (pi) * radius^2 * height

    3.14 * 1.75^2 * 9.5 = about 91 cubic inches

    1 cup = 14.44 cubic inches

    91 / 14.44 = 6.3 cups

    Drink one of those beasties a day and have a 16-ounce glass of water with supper, and you're good.

    But in case the measurements are off, I'd use the "fill it from a one-cup measuring bowl and count fill-ups until the fingers holding the bottle get wet.

    Is 3 1/2 the radius, diameter or circumference?

    If it is not squared it would be
    91/2+ 3/12= 13 Cubic Inches = 7.2 ounces

    Maybe the bottle is on its side and 3.5" is the height and 9.5" is the length.
