b. what is the volume of the prymaind?
Thanks for your help. I can not figure this out.I beleive there is one more component missing. Not sure if I need to find the area -- first.

nothing missing...

the hexagonal base is composed of 6 equilateral triangles , with side length 6

the slanted edge length of the triangles that make up the 6 sides of the pyramid is sqrt(6^2 + 8^2)

find the area of the hexagonal base and the six lateral triangular faces

the volume is ___ (1/3)(area of base)(height)
