This is a math problem

Take the numbers which make up your birthday and add them up (for example, my birthday is 3/9/64, so 3+9+64=76).  Whatever your sum is, assume that number is a certain number of miles.  Determine the conversion necessary to turn miles into kilometers.  Then take the number of kilometers you just derived and assume that is some number of square feet.  Determine the conversion necessary to convert square feet to square meters. Use this birthday 10/24/71
