Best ResponseYou've already chosen the best response.0Volume of Prism = (5/2)ash = Ah where, a = apothem length, s = side, h = height, A=area

Best ResponseYou've already chosen the best response.0oky so (5/2)ash should equal the area multiplied by the height?

Best ResponseYou've already chosen the best response.0yup\[{5\over2}\times (apothem) \times side \times height = Area \times Height \]

Best ResponseYou've already chosen the best response.07in apothem 30in length (if yu turn the prim upside the length turns into height, right?) 12 inch side length = side

Best ResponseYou've already chosen the best response.0oh okay so the length would be the height. annd why is it 5/2 at the beginning is that some sort of equation?

Best ResponseYou've already chosen the best response.0hmm.. it's from deriving the equation... it's just like the area for a triagle = (1/2)bh

Best ResponseYou've already chosen the best response.0oh is there an equation for a pentagonal prism?

anonymous

Best ResponseYou've already chosen the best response.0oh and in the equation you said it will = area* height, did you mean the area of the pentagon?
