My mistake. That's right, is your book's solution different? [math]48\sqrt3 +72[/math]

yess. it's 72+8sqrt3

Looks like they missed the 4 before the 8.

In the book it's written 8(9+sqrt3), but I guess they could have missed the 6 then. Thank you for helping.

Possibly they forgot to account for the 6 sides of the hexagon.
