Let ABCDEFGH be a rectangular prism, as shown, where AB = 2, AD = 3, and AE = 5. Find the volume of pyramid ACFH.

The area of the triangular pyramid  =

 

(1/3)Area of Base * Height

 

The area of the base = (1/2)AD * AE   =   (1/2) 3 * 5  =   15/2  = 7.5

 

And the height =  EF  = AB  = 2

 

So......the volume  = (1/3)(7.5)(2)  =  5 units^3
