Answer 2

To answer the problem above, determine first the volume of the rectangular box by multiplying the dimensions. The length is 3 feet, width is 6 inches which is equal to 0.5 feet, and the height is 2.4 inches which is equal to 0.2 ft. The volume is 0.3 ft^3. To determine the number of bags of sand needed, divide the volume or rectangular box by the volume of sand, 0.15 ft^3. Thus, Jack needs 2 bags of sand.
