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.
