Math Is Fun Forum

Okay, so to make this short and simple, I am doing a case mod on a computer case. It is going to be part light bright, and part translucent legos.

This is the case(in case you're curious): http://www.newegg.com/Product/Product.aspx?Item=N82E16811148001&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-

The measurements are: 18.5" x 8.2" x 17.5"(D x W x H)
The light bright base is: 12x12
The legos I want to use: 1x2 (transparent red base)
I just need to know how many of the 1x2 legos I would need to cover: the right side, the left side, and the top

The back,front, and bottom need to be excluded, as well as the 12x12 section of light bright.

I have tried many ways of calculating it but I keep coming up with bogus answers, that just don't sound right.

If anyone could explain how to find out how many legos I will need, please help me out! My computer comes in just a few more days, and I would like to start modding as soon as possible! Thanks a bunch!
