Ricardo wants to cover a 8" by 10" by 5" box with contact paper How many square inches of caontact paper will he need? How much ribbon will he need if the bow itself adds 15"
just do l*W*H 8*10*5 then for the ribbon just add 15 to the solution of 8*10*5 = 450 + 15 = 465 then what ever it is in m. cm. in. mm.
