Sorry, fixed it!

Thanks so much!! :D

Oh I figured it out!  Since there are 12 pentagons (12 x 5 = 60) there must be 20 hexagons (20 x 6 = 120) so together there are 180 edges but since it is a 3D object we divide that in half for a total of 90 sides.

Thank you!  Any tips for the second one?

Thanks CPhill!

Thank you Heureka, must have just been a typo haha!

Great thank you so much!

Thank you so much CPhill!

You were right! My bad, thanks!

Ok, so here's my graph:

The equation I have been told for area calculations is [(h_b)b]/2 which gave me an area of 16.9 which is incorrect.  For your method, what does "half" refer to?  

Thanks!

Thanks so much Heureka!  Still not sure what happened on the other one haha!

Thanks so much for your answers Heureka!  I think I'm having an issue with the website though.  I see on the side of my screen that there were 5 answers posted to the thread in the little (+5) notification bubble, and I had 5 questions posted here which makes sense, but on the actual post itself I only see your answers to 3, 4, and 1, in that order.  I think this might be a problem with the website but does anyone know how I can view the other answers?  I have tried reloading the site.

Thanks

Thank you Heureka!

Thank you CPhill!

Thank you!

Thank you both!
