six, you need six
To make a triangular prism using straws, you'll need a total of 9 straws: 6 for the triangular bases (3 for each triangle) and 3 for the vertical edges connecting the two triangles. Each triangle requires 3 straws to form its sides, and the vertical straws connect the corresponding vertices of the two triangles.
the answer is 12
You'll need 18 straws because it has 18 edges

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.

18 straws.
15 straws are needed
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.
