the answer is 12
To build a pentagonal prism, you would need a total of 30 straws. This is because a pentagonal prism has two pentagonal bases and five rectangular faces. Each pentagon requires 5 straws, totaling 10 for both bases, while the 5 rectangular faces connecting the bases contribute an additional 15 straws, leading to 10 + 15 = 25 straws in total.

18 of them because an hexagonal prism has 18 edges
Rectangular prism = 6Triangular prism = 5 Triangular pyramid = 4 Rectangular prism: it is still 6 Rectangular pyramid = 5.
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.
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.
15 straws are needed
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.

9 straws because it has 9 edges, 6 vertices and 5 faces
6 sides are needed
The answer depends on how large the prism is.
