If
then
The ODE in terms of these series is
We can solve the recurrence exactly by substitution:
So the ODE has solution
which you may recognize as the power series of the exponential function. Then
For a cube, 
The volume is the cube of the side length.
To raise a product to an exponent, raise each factor to the exponent.
To raise a power to a power, multiply powers.
