The following steps will help us find the constant of variation:

Step 1: Write the joint variation equation

When varies jointly as and the cube of , we can represent this relationship using the equation , where (the coefficient we are trying to find) is the constant of variation.

 

Step 2: Substitute the given values into the equation

We are given that , , and . Plugging these values into the equation , we get:

 

Step 3: Simplify the right side of the equation

First, we calculate
