10000000 pounds
it depends how tall the person is.
90-115 pounds
About 50 to 60 Lbs
about 75-100 pound if you are the right hight
it depends on your genes in your family. i would say 150 lbs. no mostly it depends on how tall you are,if your tall you should weigh more. id say a tll eight grader should weigh about 140-170 but a short eight grader, probably about 115-150
