Jack wants to fill a rectangular box with sand. The length of the sand box is 3 feet, width is 6 inches, and height is 2.4 inches. Each bag of sand contains 0.15 cubic foot of sand. How many bags of sand will Jack need to fill the box completely?
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.
Answer:
he would need 2 bags of sand
36x6x2.4 = 518.4
.15 cubic feet is 259.2 cubic inches
518.4 divided by 259.2 = 2
