David will need to divide the total number of cubic inches he needs to cover by the number of cubic inches in each bag.
Total cubic inches needed = height x area of the front yard
Let's assume the area of the front yard is 100 square feet.
Total cubic inches needed = height x 100 ft2 x 12 in2/ft2
Total cubic inches needed = height x 1200 in2
Number of bags needed = Total cubic inches needed / 3456 in3/bag
Number of bags needed = (height x 1200 in2) / 3456 in3/bag
Number of bags needed = height x (1200 in2 / 3456 in3/bag)
Number of bags needed = height x (1200 / 3456)
Number of bags needed = height x 0.346
Therefore, David will need 0.346 bags of mulch for every inch of height he wants to cover.
hi...again :/
David will fill in his front yard with mulch that is inches high. Each bag of mulch will cover 3456 cubic inches. How many bags will David need?
