    But the units are not centimeters. They are cubic centimeters. You need to convert from "cubic feet" to "cubic centimeters"
    (You went from "feet" to "cm" which is incorrect)

    I would suggest doing the conversion at the beginning of the problem

    your should be 62x29x7.3x(12x2.54)^3 cm3

    since 1 ft =12 inch and 1 inch =2.54 cm
