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
