Answer: I believe that you have to do e^3 to find the volume of a cube.
If you had the side, you would do a^3 (a stands for the side length)
Let

. Then

, and differentiating both sides with respect to

gives


Now, when

, you get

You have

, so

and

. So
y-intercept for x = 0.
Substitute x = 0 to the equation of the function:

About less than 3 inches :)
