Let \(ABCDEFGH\) be a rectangular prism, where \(EF = 4\)\(EH = 5\), and \(EA = 6\). Find the volume of pyramid \(CFAH\).

 

 

Thank you!

The volume of a pyramid is  (1/3)·(area of the base)·(height).

 

The base is triangle(AEH)

-- the area of this triangle is one-half the area of rectangle(ADHE)

-- the area of rectangle(ADHE)  =  6·5  =  30

-- so the aea of triangle(AEH)  =  15

 

The height is FE  =  4

 

So, the volume of he pyramid  =  (1/3)·(15)·(4)  =  20

That answer was incorrect. I think there was a mistake somewhere.
