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.

6 straws are needed
You just think of the triangular prism as open. How are you going to fold it to make one? It's actually really easy, I thought it was gonna be hard too!! Luv you guys bye
12 straws
3 for the top, three for the bottom a one each for connecting the vertexes make 9.
<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. :)
