Abodybuilder is 6ft 4in tall and has a body mass index of 27.6. how much does he weight?

To determine the weight of the bodybuilder and since we are given the BMI or the boddy mass index and the height, it would be best to use these values. BMI is a measurement that is used to scaled body fat based in the weight and the height of adult women and men. It is calculated by the equation as follows:

BMI = 703 (mass in lb / height in inches^2)

Given: 
height = 6ft 4in
BMI = 27.6

Solution:
height = 6 ft ( 12 in /1 ft ) + 4 in = 76 in

BMI = 703 (mass in lb / height in inches^2)
27.6 = 703 (mass in lb / 76^2)
mass = 226.77 lb or  103.08 kg
