A rigid shape is when you cant push/pull on it and make it turn into a different shape. You can make shapes rigid by adding "braces", which are lines that you put inside the shape to make triangles (which are rigid). For instance, a square is notrigid. To make it rigid, you would put a brace inside diagonally. This would create TWO triangles, and therefore, rigid. ~xDragonx

If the straw were normal and 8.25 inches then it would take 4.772121212121212... straws.
You would need 12 straws of equal sizes because a cube has 12 equal edges, 8 vertices and 6 faces
The answer will depend on what the shape is. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.

assuming the straws do not bend, you would need six
That's going to depend on what shape you're building, which, as far as I can see, you neglected to mention.
16 straws.

To build the skeleton of a triangle-based prism, you would need 9 straws: 3 for each edge of the triangle base (totaling 9 straws) and 6 additional straws to connect the vertices of the triangle to form the prism.
You would need 12 straws because a cuboid has 12 edges, 8 vertices and 6 faces
<X X> It should look kinda like the example above. Except it would be squares lol. Make two crosses with the 4 long straws put the ends of these together so that one square is made then make two right angles with the four short straws and place them at the other side of each cross to make three squares in a diagonal line. :)
i find it really dumb that answers is just basically a comment section answers! >:(
