campbell_st · Answer

add the 2 volumes   Prism: V = base area x height
                                  Pyramid  V = 1/3 base area x height

                                   the pyramid base area is the same as the prisms.

4*4*12 = 192  This is the volume of the bottom rectangular prism.
Pyramid volume is, if my memory serves correctly, Base^2 * height * 1/3
so the pyramid would be 4^2* 3* 1/3 = 16  So the total would be 208
