    You are given that f(x) is less than 50 inches so just solve f(x)<50 for x

    if you want to do the problem with the window box you need to first find the volume of the window box and then divide that by the volume of one bag to see how many bags you need

    then you multiply the width, height, and length to find the volume of the box
