On the back of the latest Private Eye magazine is an advert for the new Saab 9-3. Apparently this thing has 1273 cubic litres of luggage capacity.
Say what?
This guy got in trouble building a four-dimensional house. Buy a car with a six-dimensional boot and you’re just asking for trouble. Sure, your golf clubs will fit with no problem, but the first time you hit a speed bump you might just develop your own event horizon…
1200 liters is just 1.2 cubic meters. That doesn’t seem like all that much to me.
Yes, Excalibre, but how can you have cubic liters? They’re already cubed! Too many dimensions!
I just don’t think we’re ready for this sort of thing. There should be a massive recall before we rupture space-time.
Maybe not, but you can fit a whole bunch of whooshes in it.
Actually, on second thoughts, the boot must be nine-dimensional.
(y[sup]3[/sup])[sup]3[/sup] = y[sup]9[/sup].
Quite a USP when you think about it.
Actually 1273 cubic litres is a maximum.
I think it depends on the chosen seating configuration for a 5-door model but the available space can shrink to 419 litres.
So the boot space is really quite flexible.
I think trunk space would also be based upon how far backwards or forwards in time you place your things, and also on which temporal plane, among a host of other variables both esoteric and mind-bending.
This can of course be increased with optional bags of holding or a T.A.R.D.I.S.
Can you only carry liquid in the trunk?
Am I being whooshed too, or are people missing the point here?
A litre is 1000cm[sup]3[/sub].
A cubic litre would appear to be, um, 1 billion cm[sup]9[/sup] 
Stupid coding. Let me try that again.
A litre is 1000cm[sup]3[/sup].
A cubic litre would be one billion cm[sup]9[/sup].
Or anything that can be crushed until it assumes liquid form.
In structural engineering there are certain quantities that are dimensioned in units of cm[sup]4[/sup] (which I suppose could be called quartic centimetres?).
cm[sup]9[/sup]?
Brain. Hurts.
Just to be perfectly clear, a liter (or litre, if you prefer) is already a three-dimensional measure of volume. Per the OP, a cubic litre, I guess, would be a nine-dimensional measure.
Any string theory fans out there?
Really? I’m intrigued. What and why?
Of course, now I don’t quite remember and can’t find a reference.
The cm[sup]4[/sup] was an abstract unit that just came about mathematically; the thing it was describing wasn’t really intended to be described in quartic centimetres. It’s kind of like expressing distance in cm, speed in cm/s, and then change of speed (acceleration) in cm/s per second, or cm/s[sup]2[/sup]. There isn’t really such a thing as a “square second” (s[sup]2[/sup]) involved; we actually say “centimetres per second squared”.
Here it is: second moment of area:
Dimensioned in m[sup]4[/sup].
Maybe the Saab 9-3 is holographic with our reality’s 3 dimensions representing 9 total. The luggage space listed is describing the total available space in all dimensions.
Of course, the “total” space available in all dimensions is a misleading number, since the hyperspace OS reserves a significant proportion for itself.
And be sure to clear everything out of the trunk before you defrag it.
Or worse, “cm per second per second”.
