# rectangular dice

## Recommended Posts

Why don't they use rectangular prisms for dice?

They do, just they are not traditional. I think they may be easier to cheat with, as you could angle a throw to bring up numbers from only one side of a prism.

Plus, a square is cheaper to produce.

hmm.... it won't be fair, cause the landing on the rectangular faces is of a higher probability that on the square faces.

i doubt an rectangular dice would even roll.

What about a spherical dice? never see any of those

well, i actually have one of those!! REALLY!! I bought them when i went to England. It really can (notice i said 'can') be played with. It has a little ball inside it which gives it a weight to stop at a point. I haven't broken it! If u just jingle it a little you can here a 'tick, tick' sound, so that is my hunch!

sounds like loaded dice to me, but the weights come loose

I was thinking about a "rectangular prism" the only thing I came up with as a picture was a standard prism, 5 sides, a triangular cross section and squared at the ends, making a front veiw look like a rectangle, but wouldnt you need 2 of them for all 6 numbers?

and then what do you do if one rolls a 3 and the other 6 LOL

I'd suspect that the spherical die (it's not dice fellas, that's the plural) of, say, 20 sides would have a 20 sided interior, and the weight comes to rest on one of them.

A rectangular die would roll, just not as well or as much.

A rectangular prism is a cuboid. There's even a picture of one IN THE THREAD.

Take a look at the diagram! I think u misunderstood me!

here's what is REALLY looks like (i managed to find it!)

Oh, and don't forget that normal dice are rectangular prisms too.

##### Share on other sites

yeah! or a squarical prism!!!

##### Share on other sites

To generalise, normal dice are always regular solids.

hmmmm.... what do u think of my spherical dice. Pretty awkward isn't it?

Spherical die.

And I've seen them before.

Tetrahedral, technically. AKA a D4.

really, you think,

give him a medal

MD did you want me to expalin probabilities to you?

##### Share on other sites

No thank you IT all depends on the surface area of each face, that's all to make it simple!
