    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.

    6.5 cups.

    Hmm, I think you're right. I was going to say 7 cups, but after recalculating, 6.5 is correct.

    thank you for answering the question, I appreciate that

    This thread made my day :flowerforyou:

    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.

    but if the bottle is those dimensions you would have to multiply them to find the cubic inches.

    Look at the bottom of the bottle, it most likely has the number of fluid ounces stamped there. Then divide by 8.

    You're neglecting the fact that this is a three dimensional object. You need to find the area of the base and then multiply times the height. I have done that at the top of this page assuming that 3.5 is the diameter of a cylindrical bottle.

    Get a kitchen scale. Place the empty bottle on the scale; "zero out" or even the scale so the bottle is now weighing "0" (anything you now add to the bottle will be accurately weighed). Fill the bottle up with water and place it back on the scale.

    There are 8 oz in a up. Finally, divide the ounces by 8 to get your number of cups.

    Fill the bottle, then pour it into a measuring cup or bowl.

    You just had to be different, didn't you? ;-)

    Why not just use a measuring cup and fill it up cup by cup and see how much is in it then?

    I know that it really sucks how MFP won't let you input your water intake AFTER you've already drunk from the bottle, else you could just wait until you got home to measure how much water it holds and then click the arrows. I think you should ask them to add that to the needed features.

    no, she didn't ask the answer to life, the universe & everything... besides, since Dougie was a Brit that's probably in metric

    :laugh:

    I believe the question would fall under "everything," which means 42 is indeed correct.

    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.

    maybe she's drinking out of this??

    That's not square. That's a rectangular pyramid.
