Question 908510
Assign some variables.
w for weight
h for height
k proportionality constant


weight is directly proportional to the cube of height in inches.
Notice, "DIRECTLY PROPORTIONAL".
{{{highlight(w=k*h^3)}}}


Next are given, h=5, w=108.
You need to use this to find the value of k.
{{{w=kh^3}}}
{{{w/h^3=k}}}
{{{k=108/5^3}}}
{{{highlight_green(k=108/125)}}}
The formula is {{{highlight(w=(108/125)h^3)}}}


Finally the question is to find w if h is 5 feet 10 inches.  Convert this into a decimal value
OR into an improper fraction, but finish the result as either decimal value or mixed number.
