help me with pyramid puzzle (Lenny Conundrum)

[Lilac Smith]

The base of the pyramid is 100 blocks by 100 blocks; each successive layer is one less block wide and deep, until the top layer which is simply one block. Each block is 97 cm wide by 97 cm deep by 63 cm tall.

If one liter of paint can coat exactly three square meters, how many liters are required to coat the entire exposed surface of the pyramid? Round up to the nearest liter.

Note to the tutors: This isn't a math question, which is why the poster isn't going to put any effort into this. It's the latest Neopets "Lenny Conundrum" puzzle contest, and the poster is expecting you to put in the work to win her some prizes.

well I never said it was school work. I did put some effort into it but can't figure it out. I'm not expecting for someone to give me the answer just some idea of how to solve it. Next time please read carefully before you accuse people.

If you did do some work, then you at least got this easy part:
how many blocks is there in total?
