Title: Re: maths question??? Post by: doubleup on January 24, 2009, 07:03:16 PM I'm going for 5
I googled it and its 3 or 5 depending on whether one of the faces is square Title: Re: maths question??? Post by: Dino on January 24, 2009, 07:13:30 PM 9 if it is a cube,3 if it is not.

Post by: boldie on January 24, 2009, 07:14:19 PM 9 if it is a cube,3 if it is not. 9? how did you come to that? Title: Re: maths question??? Post by: cia260895 on January 24, 2009, 07:16:14 PM it is definitely a cuboid
he put 3 and seeing as its the most common ansewr i'lll go with it wd all that said 3 extra homework for those that didnt :cheers: Title: Re: maths question??? Post by: Dino on January 24, 2009, 07:22:46 PM a cube is still a cuboid in the same way a square is a rectangle.
Title: Re: maths question??? Post by: boldie on January 24, 2009, 07:29:41 PM a cube is still a cuboid in the same way a square is a rectangle. Doesn't explain how you came to 9 though. Title: Re: maths question??? Post by: Dino on January 24, 2009, 07:30:10 PM There is a diagram about halfway down here (http://www.mathematische-basteleien.de/cube.htm#Symmetries of a Cube) which shows the nine.
Title: Re: maths question??? Post by: Robert HM on January 25, 2009, 01:33:16 AM A = P(1 + r/q)nq
Title: Re: maths question??? Post by: cia260895 on January 25, 2009, 09:02:44 PM A = P(1 + r/q)nq now if you had explained it like that earlier i would have got it.. Title: Re: maths question??? Post by: Chompy on January 25, 2009, 09:40:56 PM Is it multi-dimensional?
