Best ResponseYou've already chosen the best response.0ehh, nahh. i'll just attempt to explain. okay so each side of the base has a length of 16 cm. Then the base has a annulus of 11. And it looks like the height is 36 cm

Best ResponseYou've already chosen the best response.0http://www.mathsisfun.com/geometry/pentagonalpyramid.html gives us the volume as: 1/3 [base area] times height

Best ResponseYou've already chosen the best response.0Area = 16^2(1.7)(36)/3 is what it looks to be. pentagon

Best ResponseYou've already chosen the best response.0oh. ha. okay. so you took 16 to the second power , but where did u get 1.7?

Best ResponseYou've already chosen the best response.01.7 is what someone smarter than me got when they figured out the formula for the area of a pentagon :) s^2(1.7) = area of pentagon

Best ResponseYou've already chosen the best response.0you said the height was 36. (1/3) (base area) (height) base area = (side^2)(1.7)
