That's going to depend on what shape you're building,

which, as far as I can see, you neglected to mention.

How many straws would you need to make a dodecahedron?

There are various types of dodecahedrons. A regular dodecahedron has twelve faces, each with five edges. Altogether there are thirty edges. So you could make a regular dodecahedron with thirty straws, or one very long one! You could even make one with sixty straws, but you would have to join them together in pairs to make the thirty edges! For more information, see 'Related links' below this box.


How many straws would you need to make a triangular prism?

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.


How many straws needed to make a rectangular prism?

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.
