62x29x7.3= 13125.4
Then I converted it to cm and got 400062

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
