BASE OF PARALLELEPIPED IS RHOMBUS WITH AREA OF 1m^2. IF THE AREA OF CROSS
SECTIONS
ARE 3m^2 and 6m^2 (diagonals)THEN VOLUME OF PARALLELEPIPED IS ?
RESULT IS 3m^3,how???
If d1=asqrt(2) and d2= asqrt(2) ...6=h*d1...6=h*asqrt(2)..6=h*1*sqrt(2)
d=asqrt(2)
d1=6 sqrt(2)
d2=3 sqrt(2)
then h= 2
If area of rhombus is 1m^2 then a=b =1

and V=a*b*c=1*1*2=2 this is not correct(I` mean result should be 3)
What is wronge with this picture?????



Please help!!!

Thanks
 
Is that you, Niki?

I had to guess where the cross-section were ... and posted a solution at MMB.
. . (Sorry ... the tutors at this site are no more telepathic than at MMB.)
 
"parallelepiped"

Methinks I'll start a petition to get that name changed...
 
Hy Denis!

I` wrote parallelepiped because I` copy it from a dictionary so if there is wrong I` write it to in wrong way. And by the way if you are not interested in writing to help someone way do you trouble your self.

Niki ,hope ...

I` just show that I` wrote before(at first time I` write) where are the cross -sections.

Don't get all excited, hope...it is the correct spelling;
I personally never liked that word (reminds me of multi legged creatures)
and put that up as a joke...NOT addressed to your post whatsoever...
 
I`am so tired of learning so it seems a bit angry, but I` am not angry just
misuderstood and I` would like to clarify things, and I` am very thankful to all of you only a little impatient.
So...
