cuboid dimension 3in x 12in x 4in

wrapped present has two loops of ribbon around it. each loop goes completely around the box once and always runs down the middle of a face. The two loops overlap each other at a right angle, but ends of the ribbon do not overlap when making loop. How many inches of ribbon were used?

(not sure how cuboid formula to be used? any hint or help will be appreciated)

Well You know that the height is 4 and the length is 12 and the width is 4 so add 4+3+4+3 to see the ribbon that goes around the body of the cuboid, which is 14.Then add 12+4+12+4 to see the longer body, which is 32.So add 14 and 32 and get 46in.!
