Spoiler for No...not what I meant...No, you missed the "viewing from the side" part of my post. Viewed from the side, the coins look like lines ;P. Also, the OP doesn't specify the coins have to be the same coin, so you could do it easily by using 2 coins that have a diameter that is 2X and 3 coins that are a diameter of X, which, viewed in the third dimension, are lines with those lengthsHai! That is yes..5 coins w/ 2 double diamater. Looks like a parallelogram with line in the middle.
OP should say "same coin" but i guess no one use 4 half-cut coins (or bitable coins) to make 8 diameters.
Spoiler for thru manifying lens
My angles were more...90 degrees
.
Sorry if I'm going on a completely different tangent than what the OP intended, to be honest, I'm not sure what the OP intends
, but seeing your response to witzar made me think 'outside the box' (or plane of the box
) type solutions were acceptable.
