i'm not asking for the answer, i'm just curious if theres an easier way to get the area of the base of this pyramid. (https://media.glynlyon.com/a_matgeo_2011/7/groupi75.gif) then having to find the apothem find the area of one (of 12) right triangles, then multiplying that by 12 to get the area. IF that is even a correct method.

Find area of one right triangle there are 2 for each side and there are 6 sides. it will be 12 times that right triangle.

but i still have to find the apothem yes?

OpenStudy (kinggeorge):

That's the most direct way, but since this is a hexagon, it's formed from 6 equilateral triangles. You could use the formula \[{\sqrt{3}\over4} (4^2)\]to find the area of a single one and then multiply by 6 to find the area of the base without finding the apothem. However, this only works since you have a hexagon.

OpenStudy (kinggeorge):

But then to get the height of the pyramid, it looks like you still need to find the apothem, so this would just make the problem more complicated.

well i'm out to find the volume and a bunch of other things, so i guess i do need the apothem.
