In a ABCABC packing of giant buckies (C-240);Bucky babies-Chotu (C-32) and Motu (C-44) are doped in tetrahedral and octahedral void respectively . In the unit cell thus created all balls along any one body diagonal are removed and Bucky onions 240 contains C-60 suspended inside it with centres coinciding are fitted at either extremes. Calculate the number of C atoms finally present in the unit cell.
