Problem:
Mommy says Daddy is fat, but Daddy does not completely agree. Daddy is 102kg in weight and 186cm tall. Daddy used to be a swimmer and does some weights and push-ups every morning, but could stand to loose 5 to 10kg.
Generally speaking, the weight of a person increases to the ration of the cube of their weight.
Daddy knows a man who is 190cm tall. Assuming that the man's body has the same general structure, and muscle / fat ratios, how heavy should that man be?
Answer (please verify): (190/186)3 X 102= 108.72kg, or about 239 pounds.
