    To calculate the amount of concrete needed for the sidewalk, we need to first calculate its volume.

    The volume of the sidewalk can be found by multiplying its length, width, and depth. Since the width is given as 5 feet and the depth is given as 0.75 feet, we have:

    Volume of sidewalk = Length x Width x Depth = 260 ft x 5 ft x 0.75 ft = 975 cubic feet

    However, concrete is usually measured in cubic yards, so we need to convert cubic feet to cubic yards.

    1 cubic yard = 27 cubic feet

    Therefore,

    975 cubic feet ÷ 27 = 36.11 cubic yards (rounded to two decimal places)

    So, we need \approx imately 36.11 cubic yards of concrete to fill the sidewalk to a depth of 9 inches.
