Magtanggol loves to play with building blocks. He has building blocks in the shape of a cube. The shape and size of all the blocks are the same. Each edge of the block has a length of ^@ 3 \space cm ^@. This time Magtanggol tries to form columns by placing the blocks one over the other. He places the blocks in such a way that there is always a block less in the consecutive column. If he starts with ^@4^@ blocks in the first column then what is the volume of the resultant figure?
A piggy bank contains ^@14^@ ₱1 coins, ^@10^@ ₱2 coins, ^@34^@ ₱5 coins, and ^@30^@ ₱10 coins. If it is equally likely that one of the coins will fall out when the bank is turned upside down, find the probability the coin falling out will be of value more than ^@₱5^@.
