    Answer:

    112.46 yd³

    Step-by-step explanation:

    1 inch = 0.0278 yds

    1 feet = 0.333 yd

    Thickness = 4 inches = (4 * 0.0278) = 0.1112 yds

    Width = 3 feets = (3 * 0.333) = 0.999 yds

    Length = 40 feets = (40 * 0.333) = 13.32 yds

    Volume of sidewalk :

    Thickness * Width * Length

    0.1112 * 0.999 * 13.32 = 1.479702816 yd³

    1 yd³ of cement = $76

    Cost :

    1.479702816 yd³ * $76

    = 112.457414016

    = 112.46 yd³
