The description of the [*Light*](https://www.dndbeyond.com/spells/light) spell in D&D 5e says:

> 
> You touch one object that is no larger than 10 feet in any dimension. Until the spell ends, the object sheds bright light in a 20-foot radius and dim light for an additional 20 feet. (...)

**Can I cast the *Light* cantrip on an 11-foot pole?**

On one hand, 11 is greater than 10. This would suggest that the answer to my question is "no".

On the other hand, I could put an 11-foot pole in a 10×10×10-foot box. This would suggest that the answer is "yes".

I don't expect that the success of an adventure will hinge on the answer to this question any time soon, but I would like to understand how dimensions are supposed to work.
