    Default What does # cu. ft. even mean?

    There is a huge debate going on, on other forums, in which people are trying to figure out what cubic feet even means.

    For example, a 10th-level caster can cast shrink item on one touched object of up to 20 cu. ft.

    One group is arguing that, that is twenty 1-ft. cubes in any configuration (so if you lined them up side by side, you would end up with a 20x1x1 shape).

    The other group is arguing that it means 20x20x20.

    Which is right?

    It looks as though proper math supports the former, but game sense supports the latter. After all, what is the point of shrinking an object that is already REALLY small? (A 20th-level caster gets 40 cubic feet with shrink item, which according to the first group would mean he could only shrink an item that is 3.42 x 3.42 x 3.42 feet)

    This effects other spells as well, such as the Stone Shape spell. A 10th-level caster with the former interpretation can barely make a passage through a wall. A wizard operating under the latter interpretation could probably shape himself a small house.

    A math major friend of a friend (not joking) tells me that the former interpretation is for #^3, or feet cubed, and that the latter interpretation describes cubic feet (which is what the rules refer to). However, I have found web sites that say cubic feet is as per the former interpretation.

    Hope I haven't confused you all.

    The first one is right mathematically.
    Our group has always followed that as its ruling.

    You mean the 20x1x1 group?

    Okay, but do you believe that to be the INTENT of the rules?

    Are you sure you're not just getting 20 cubic feet mixed with 20-foot-cube in your head?

    The right answer is the first one, of course. It's an area equivalent to 20 1-ft cubes.

    For Reference: Shrink Item

    Note:
    Target: One touched object of up to 2 cu. ft./level
    So in the debate a tenth level wizard is casting this spell to get the required 20 cu. ft. Correct?

    The measurement of Cubic feet is one of volume in can be annotated as ft3 or as cu. ft. both refer to the space inside a 3 dimensional figure. Since the distance is not measured in feet, for example Fireball, it already is a measurement of volume.

    In short: The first interpretation (i.e. 20 1-ft cubes in any configuration) is the correct one.

    But wouldn't that mean that a 20th-level caster could only shrink a cubed object with a little less than 3.5 feet on a side? That's ridiculous!

    A 20th-level wizard should be shrinking large boats, not small chairs.

    Not exactly a definitive RAW answer, but the intent of stone shape seems similar. Besides, each caster level gives +1 Cubic foot area, so it's rather easy to get irregular numbers.

    As everybody else has said.

    The other one would be "twenty feet, cubed" which sounds similar but is very totally different.

    There really is only one answer. A 20' by 20' by 20' cube is 8000 cubic feet. The spells pretty clearly mark in said situation to be 20 cubic feet, which could be a 20'-1'-1', a 5'-2'-2', a 4'-5'-1', or whatever other dimensions you desire. cubic feet is a measure of volume, and is fairly consistent.

    On the other hand, if you look at say, fire storm, its area is listed as "two 10 ft. cubes per level (S)," so instead of a 13th level caster getting 260 1 ft. cubes to shape as he or she wills, she instead gets 26 cubes that are 10 feet on each side to shape. There's a clear difference in wording.

    I don't know where your math is coming from as I just got 13-1/3 feet to a side for the final figure (2*20/3 PEDMAS rules state that 2*20 (40), then 40/3 (13.3 repeating or 13-1/3).

    Also as wizards, by 5th level, completely dominate every other class in the game, I fail to see the lack of boat shrinkage to be a problem.

    It seems your friend [can't/couldn't] tell the difference between (20 ft) ^ 3 and 20 ft ^ 3.

    It really is a simple question, your friends are probably only really arguing because of momentum. Once one person sets an argument in motion, it stays in motion; mostly because nobody wants to look stupid.

    And here's the thing: Shrink Item is only a third level spell! Do you really expect the third level spells to still be impressive at level 20?

    More likely to be a physics course. You stop doing actual math when you're a math major and start screwing up your head with absurdly specific calculus.

    His math is correct. You take the cube root, not divide by 3. I always saw the use of Shrink Item as keeping all those pesky items stored. It's much easier to carry loot when you can take 4,000 times more.

    A 20th-level wizard casting shrink item can shrink a touched object of up to 40 cubic feet, yes?

    So by everyone's definition here, that means...

    Oh.

    I see what you mean.

    The math I WAS using was:

    40 ^ (1/3)

    Or the cubed root of 40.

    Argh! I've been tricked!

    Further evidence that it is NOT SIMPLE AT ALL!

    A wizard likely doesn't have 4,000 castings of the spell prepared, however.

    I think you misunderstood. Your math, saying that about 3.5 ft/side was 40 ft^3, was correct.

    Generally refrigerators are measured by internal space, so...less than 2, but more than 1.

    a cube 3.5 ft to a side = 42.875 cubic feet. A 20th-level wizard can only shrink an object that is 40 cubic feet.

    That doesn't strike anyone else as seriously FUBAR?

    Such an object is Small-sized. If that was the maximum volume of the spell pre-epic, why would it even bother saying the object is four sizes smaller? You can't even go four sizes smaller than small!

    This would be a good question to ask on the offical forums.


    Also, cubic foot =/= foot cubed.

    By one reading, the sane way, yes, it's a bit underpowered at 20. However, the other way is to shape it so that you are only shrinking the mass that you want shrunk, and not the air inside of it. Admittedly, you won't be shrinking large sailboats, but you just might be able to shrink a barge.

    Other possible methods would be multiple castings on 40 cubic feet of wood each, followed by permanency and several months of craft checks. Set all the castings to one key word, and you can craft a fairly large boat for yourself that's the size of the parties fighter and much more useful.

    At what caster level is that though? If it's 20th, then it does little good when you first pick up the spell.

    I read all the time about people shrinking and dropping boulders. I'm beginning to realize that these boulders must have been really, REALLY small even before being shrunk.

    Other spells that use the cu. ft. terminology:
    - fabricate (@ CL 20th can build a 5.85 x 5.85 x 5.85 foot object)
    - major creation (@ CL 20th can create a 2.7 x 2.7 x 2.7 foot object)
    - make whole (@ CL 20th can repair a 5.85 x 5.85 x 5.85 foot object)
    - minor creation (@ CL 20th can create a 2.7 x 2.7 x 2.7 foot object)
    - shrink item (@ CL 20th can shrink a 3.42 x 3.42 x 3.42 foot object)
    - stone shape (@ CL 20th can shape a 3.10 x 3.10 x 3.10 foot object)

    Some of these spells are next to useless as written. Surely the game designers meant feet cubed, rather than cubic feet (in fact one told me so a long time ago, sadly I can no longer find the reference as the v3.5 boards are no more).

    Items use the same terminology in places as well:
    - bags of holding (the biggest can only hold a 6 x 6 x 6 foot item)
    - hand haversack (largest pocket can only hold a 2 x 2 x 2 foot item)

    Most of the above parenthetical sizes are rounded up. Also, I am well aware that you can make irregular shapes, I just that cubes make for easy representations.
