Answer:
The formula is an arithmetic sequence ... plus the blocks in the four lines of symmetry: 4(22 + 20 + 18 + 16 + 14 + 12 + 10 + 8 + 6 + 4 + 2) + 4(24) = 4(132) + 4(24) = 624 blocks. There are 624 blocks covering the four faces of the pyramid. Each face has 132 blocks plus the 24 blocks in each line of symmetry.
