    Setting up Double Intergrals to Calculate Volume

    Okay I managed to figure it out after reading: http://mathinsight.org/double_integral_volume My boundaries were correct but the equation I was integrating was not. It explained that the integral equation is not f(x,y) but f(x,y) - g(x,y), in my case g(x,y) being the "other surface" or z = 5 As...
