yay! so in a 5 x 5 x 5 grid there would be 48
and in a 10 x 10 x 10 there would be 315 and so on.
You have been soo incredibly helpful thank you so much.

3(3+2)(2*3+1)-1/8
3(5)(7)-1/8
3*35-1/8
105-1/8
104/8
=13

Thanks sooo much.
Is the John Conway formula always over 8 no matter what the number you are using?

Im sorry to be painful but I cannot work it out if you have time can you please show me step by step so the formula and what im putting into it makes sense.

Thanks so much

thanks,

that seems very complicated, will that formula work for all triangle grids no matter what the base number? Is there an equation that is standard for all triangles?

Thanks

I need some help to find an equation to work out how many triangles are in a 4-triangle, I know the answer is not 16 and I know there is an equation to work this out but I cannot figure it out.

Can someone please help and explain it to me please.

Thanks Heaps
