Question 151219: A mounument is made in the form of a right pyramid with a regular hexagon as a base. Each base side is 5 m and the slant height is 30m. If the monument is to be covered by metal, how many square meters of metal are needed to cover the sides of the pyramid?

Okay this is good one,
What is asked is square area on the sides, so we need to recall the AREA in finding for hexagonal based pyramid.
For the formula, we need to get the Area of the highlight%28base%29 + the Area of the triangles--> that are 6 because it's hexagonal right?
But, what is ask is ONLY the AREA on the sides of the pyramid, not including the base. Good!
Our working eqn, --------> SurfaceArea=%281%2F2%29%28BaseSide%29%28SlantHeight%29*6
SA=%281%2F2%295m%2A30m%2A6
SA=450m%5E2----------> Area of the hexagonal sides
*note: want to take the whole area, go to www.argyll.epsb.ca/jreed/math8
