From the height of the equilateral triangle formula, we can find the height
h=a√3/2
=6√3/2= 3√3

IMO answer will be C

Silly question, but how do we know that the height corresponds to the second largest side x√3?

The side opposite to the 60-degree angle is height. And from the 30-60-90 triangle property, the side opposite to 60 is x√3.
