Danny needs to buy sand for this box. He wants to nearly fill the box leaving only 6 inches empty at the top. How much sand does Danny need if the length is 12 feet the width is 2 feet and the height is 3 feet.
I first found the volume which was 72 feet and since 1 ft=12 inches and he only was 6 inches empty I did half of 1 foot and I got my answer which was 71.5 ft of sand

  1. sand height is 2.5 feet (3' - half foot)

    12 * 2 * 2.5 = 12 * 5 = 60 ft^3
