if thar was a tower that has 1 block on the top and in order to add a level u add 4 blocks to the last level
so how many blocks ar on the 58th level??
So IF I'm getting the problem right, this will be in a sequence.
floor level = n
n=58 (since you said it was 58th level)
58*4 = 232
232+1 = 233
there you go. Hope i got the problem right.
