.
The weight w( in kilograms ) of a milkfish is related to its length l (in centimeters ) 
by this function : w = (9.37×10⁶)L3.
Find the inverse of the function . Then determine the approximate length of hake that weighs o.679 kilogram.

In order for to get how absurdist the  " problem "  is,

substitute a typical length of a milkfish  (~ 1  meter,  or  100  centimeters) 

into the formula,  and calculate the weight.



After completing it,  throw this  " problem "  to closest garbage bin.
