Question 656242: If all men had identical body types their weights would vary directly as the cube of their heights. Robert Wadlow was 8 feet 11 inches tall (107 inches) at the time of his death. If a man who is 5 feet 10 inches tall (70 inches) with the same body type as Mr Wadlow weighs 170 pounds, what was Mr Wadlows weight?
