Hey plz can some1 help me find the slant height, height, and area face (area of face i guess) of an octahedron?? Please its urgent really urgent
@mathslover
@nikato do you know this?
It has an edge of 6.8
oh and i need base area too :/
Elisa - Please refer to this link - http://www.math.ubc.ca/~cass/courses/m308/projects/cchang/webpages/octahedron.html
i couldnt really comprehend it, but if you cant help me with this can you clarify an answer for me? i did base area for a regular tetrahedron with an edge of 10.4 and then i ended up getting 27.04sqrt3
some1 else helped me but i doubt that answer...
you're working on octahedron or tetrahedron ? which question you're stuck at ?
Most importantly i need the octahedron stuff which is slant height, base area, height, and area of face , and it has an edge of 6.8
total Area of octahedron = \(\large 2 \sqrt{3}~ s^2\) \(\large s = 6.8\)
since an octahedron has 8 faces, dividing the total Area by 8 gives you `area of a single face`
i got 20.02
should be right if your calculation is correct
^thats the area of one face
yeap and how do i get slant height, or height, or base area now ? :)
` slant height, base area, height` can you define these ?
tbh, idk what they refer to... if you can tell me what they're we can find htem

that edge is a side of length 6.8, can u show me what `slant height` and `height` are on the figure ?
|dw:1399445666824:dw| i think im not sure about the slant height
easy : slant height = height of equilateral triangle of side 6.8
