You can find the area of the base using the technique Stephen used in his response to an earlier problem. o find the height I added a line to your diagram as well as some labels. The height of the pyramid is the length of the side AB of the right triangle ABC. AC = 6 and BC you found in determining the area of the hexagonal base. Thus you can use Pythagoras theorem to find AB. I hope this helps,
