Answer
h$\approx$ = 55.7 inches, rounded to the nearest tenth
Work Step by Step
In the question, we are given the weight of the boy, which is w=85
We are given the equation required, which is w=0.00185$h^{2.67}$
Through substitution, we get the following:
85=0.00185$h^{2.67}$
$\frac{85}{0.00185}$=$h^{2.67}$= 45946
h=$\sqrt[2.67] 45946$
h$\approx$ = 55.7 inches
