Question

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? [1 foot = 12 inches] numerical answers expected

Answer 1

3 feet = 36 inches

36 x 6 x 2.4 = 518.4 cubic inches

1 cubic foot = 1728 cubic inches

518.4/1728 = 0.3 cubic feet

0.3/0.15 = 2

he will need 2 bags
