Cube, cuboid, and sphere

Volumes of a cube and a cuboid are in ratio 3: 2. Volumes of sphere and cuboid are in ratio 1: 3. At what rate are the volumes of cube, cuboid, and sphere?

Result

x = (Correct answer is: 9:6:2)

Solution:

$$\begin{gathered} c:p=3:2 \\ s:p=1:3 \\ c:p=3:2 \\ p:s=3:1 \\ c:p=9:6 \\ p:s=6:2 \\ x=c:p:s \\ x=9:6:2 \end{gathered}$$
