Construct a square on one side of an equilateral triangle. On one non-adjacent side of the square, construct a regular pentagon. Then, on a non-adjacent side of the pentagon, construct a hexagon. Next, continue by attaching a regular heptagon followed by an octagon, each on a non-adjacent side of the previously mentioned shapes respectively. To increase complexity, on a non-adjacent side of the octagon, attach a regular nonagon (9-sided polygon). Calculate the total number of external sides visible in this new configuration.
