The volume of a shape is the amount of space in it.
<em>The volume outside the cylinder, but inside the cube is 214.6 cubic inches</em>
The given parameter is:
---- length of the cube
So, the volume of the cube is:



The volume of the cylinder is:

The diameter (d) of the cylinder equals the length of the cube.
This means that:


Divide by 2 to calculate the radius of the cylinder


Also, the height of the cube is::


So, we have:





So, the volume (V) outside the cylinder is:



Hence, the volume outside the cylinder is 214.6 cubic inches
