hello
i want to calculate the surface area in terms of its dimensions a , b and h of the following rectangular geometry.
here in each step the four small rectangular cube will be added at four corner of the primary cube and having dimensions of a/2, b/2 and h and similarly in next step again four cubes will be added at the all corners of the just previuos rectagular cube and this process will go on.....
so i want to calculate the formula for surface area of the all five faces except the lower one of the cubes by changing only n (no. of iteration............).
plz help me..........[/img]
