    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
