You'll need 18 straws because it has 18 edges
A triangular prism has 5 faces: 2 bases that are triangles, and 3 rectangles.
six, you need six
A triangular prism has five faces.

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.
