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.
To create a triangular prism using straws, you would need a minimum of 6 straws. This is because a triangular prism has two triangular faces and three rectangular faces. Each triangular face would require 3 straws, and each rectangular face would require 2 straws. Therefore, the total number of straws needed would be 2 (for the triangular faces) + 3 (for the rectangular faces) = 6 straws.

To calculate the number of straws needed to make a rectangular prism, you would need to determine the dimensions of the prism (length, width, and height) in terms of the length of a single straw. Then, you would calculate the total number of straws required by multiplying the number of straws needed for each dimension. For example, if the prism is 10 straws long, 5 straws wide, and 3 straws high, you would need 10 x 5 x 3 = 150 straws.

6 straws are needed
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.
If the straw were normal and 8.25 inches then it would take 4.772121212121212... 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.
