**Reiny**, Friday, May 3, 2013 at 10:09pmThe volume of any "pointy thing" is

(1/3) base x height

our base is a hexagon where each side is 60/6 or 10 cm

of course we have 6 equilateral triangles

the area of one of these is

(1/2)(10)(10)sin60° = 50√3/2 = 25√3

and we have 6 of them, so the area of the base is

150√3

Volume = (1/3)(150√3)(30) = 1500√3 cm^3
