One type of lubricating oil weighs approximately 52 pounds per cubic foot, or 7 pounds per gallon. A 42-gallon barrel will hold approximately how many cubic feet of such oil?

    Ugghh, time to go metric.


    42 gallons weigh 7(42) or 294 pounds

    each cubic foot weighs 52 pounds
    so the number of cubic feet = 294/52 = 5.654 ft^3
