Explanation:

Step1: Convert height to inches

Since 1 foot = 12 inches, 6 feet 4 inches = 6×12 + 4 = 76 inches.

Step2: Substitute values into formula

Substitute $W = 159$ and $H = 76$ into $BMI=\frac{705W}{H^{2}}$. So $BMI=\frac{705\times159}{76^{2}}$.

Step3: Calculate the result

First, calculate $705\times159 = 112095$ and $76^{2}=5776$. Then $BMI=\frac{112095}{5776}\approx19.4$.
