16 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.
