How to i add the return values of a loop

I'm new to python a and I need to add the return values of a loop. the program is supposed to open a file containing dimensions in the format 1x31x6 sort them and do some math. I'm fairly certain I have everything right but I cannot figure out how to add the return values together. here is the code I have so far.

def parseAndSort(string):
    """this function reads the input file, parses the values, and sorts the ints from smallest to largest"""
    int_list = string.split('x')
    nums = [int(x) for x in int_list]
    nums.sort()
    length = nums[0]
    width = nums[1]
    height = nums[2]
    surface_area = (2 * length * width) + (2 * length * height) + (2 * width * height) + (length * width)
    tape = (2 * length) + (2 * width) + (length * width * height)
    return surface_area


def main():
    file = input('Please Input Measurement File :')
    try:
        output = open(file, "r")
    except FileNotFoundError:
        print("Error, please input a dimension file.")
    else:
        for ref in output:
            parseAndSort(ref)
        output.close()


if __name__ == "__main__":
    """ This is executed when run from the command line """
    main()

I'm assuming you mean you would like the sum of the return values of all the times you ran the function. You can keep a running sum, and keep adding each return value to it.

def main():
    sum = 0
    file = input('Please Input Measurement File :')
    try:
        output = open(file, "r")
    except FileNotFoundError:
        print("Error, please input a dimension file.")
    else:
        for ref in output:
            sum += parseAndSort(ref)
        output.close()
        print (sum)
