Figure Out The Number Of Blocks.

Our class had to figure out a pyramid of blocks. Our teacher made us figure her wonderful Master piece. It wasn't really a master piece it was to crooked to have been a master piece.  She made us figure all the blocks she used. I thought it was 430 some people thought it was 221.

This is the picture

This is my working out I did. This what it looks like

+ 117
+ 77
+  45
+  21
+   5
= 430
