Wouldn't I find the volume of each figure and then add ?

OpenStudy (wolf1728):

The bottom cube is 3 cm by 3 cm by 3 cm making the volume of the bottom 27 cc

OpenStudy (studyworking203):

Yes but the thing is I don't know how to find the top being a Pyramid V=1/3 B*H? I don't know some of the info...

OpenStudy (studyworking203):

I only know the height of the pyramid?

OpenStudy (wolf1728):

Pyramid volume = length * width * height / 3 Pyramid volume = 3 * 3 * 2 / 3 = 6 cc

OpenStudy (anonymous):

\[3^3+\frac{3^2 2}{3}=33 \]

OpenStudy (wolf1728):

Now, simply add 27 cc + 6 cc

OpenStudy (studyworking203):
