eye in the sky (class 3 ship) (formerly known as illuminator)
this recon vessel is equipped with sophisticated surveilance technology, that scans the area for foreign fleet signatures like the deep scan probe.
it is only fully functioning in interaction with a pyramid-device at your base. it is exposed a strong radiation that interferes with every cloaking technology, so a fleet with it cannot be cloaked and on battle contact it will disintegrate

How do I find the surface area of this hexagonal pyramid? It is a regular hexagonal pyramid. One edge of the base is 5.5cm, and one lateral edge is 9cm. I am wondering how I would find the slant height of one face and the area of the base.

maybe I am a bit slow, but where does it say that the pyramid device is hexagonal?

Or do you just want the math for a hexagonal pyramid?

A pyramid with a hexagonal base. The edge length of a hexagonal pyramid of height h is a special case of the formula for a regular n-gonal pyramid with n=6, given by

e=sqrt(h*h+a*a), where a is the length of a bottom edge

The volume of the hexagonal prism is

V=sqrt(3)*h*a*a/2

Weisstein, Eric W. "Hexagonal Pyramid." From MathWorld--A Wolfram Web Resource. http://mathworld.wolfram.com/HexagonalPyramid.html

Finding the bottom surface seems rather easy, no?

Since it is a symmetrical pyramid, all corner angles must be the same, in this case 120 degrees. So you can split the bottom surface into 6 identical triangles with all sides 5.5 by just drawing a line from all corners into the centre, no? So the corner angles must be 60 degrees for all the 6 separate triangles. Then is simple trig after that.

sure, otherwise it would make the deep scan probes obsolete
