An octagonal-based pyramid has 8 side edges and 8 base edges. For the side edges, you would need 8 whole straws, while for the base edges, you would need 4 quarter straws for each base edge, totaling 8 quarter straws. Thus, you would need 8 whole straws for the sides and 8 quarter straws for the base, giving you a total of 8 whole straws and 8 quarter straws.
16 straws.
An octagonal prism has 8 side edges and 8 base edges. If you use whole straws for the 8 side edges, you'll need 8 straws. For the base edges, since you're using quarter straws, you would need 4 quarter straws for each of the 8 edges, totaling 32 quarter straws. Therefore, you would need 8 whole straws and 32 quarter straws.
To create an octagonal base pyramid, you will need a total of 17 straws. This includes 8 straws for the edges of the octagonal base and 9 additional straws to connect the apex of the pyramid to each vertex of the octagon. The structure requires careful assembly to ensure stability and proper angles.
An octagonal pyramid has 16 edges.
An octagonal pyramid has 9 faces and 14 edges. The base of the pyramid is an octagon with 8 faces, and the pyramid itself has an additional triangular face. The edges consist of the edges of the octagon base and the edges connecting the base to the apex of the pyramid.
