Homework Help: How do you find the average value of a function on a surface?

  1. Mar 29, 2012 #1
    1. The problem statement, all variables and given/known data
    find the average value of (1+4z)**3 on the surface ....

    2. Relevant equations

    3. The attempt at a solution
    All I really want to know is how to go about this? Is the average value on the surface just the surface integral over the area of (1+4z)**3?

    It's the integral of (1+4z)^3 over the surface divided by the area of the surface.
