Theresa:
Per your formula, B=(705w)/h2, where w=weight in pounds and h=height in inches.
From the info provided, we know that B=25 and h=74 inches (6ft * 12 inches per foot + 2 inches).
Substituting these values in the formula, we get: 25=(705w)/(74*74)
25=705w/5476
Now, solving for w, we get w=(25*5476)/705=194.18 pounds (rounded to nearest hundredth).
Hope this helps.
