Yeah. That's right! I figured out the actual dimensions for the Mask of Creation out of sheer boredom! Here's both my reasoning and my evening's work!
Okay! In G1, the Toa were approximately 7 feet tall. Assuming that carries over to G2, the Toa are the same size as Kulta, the Skull Grinder. Ekimu is half his hight, as demonstrated here!
That would make him 3.5 feet tall. In proportion, the mask would be about 1.75 feet tall, as the actual piece is about 2". Upon further measurements, it is also 1" long (deep) and 1.4" wide, with the volume being 2.8 in. squared.
In proportion to the height, the mask would be 10.5" long and 10.92" wide. This makes the volume 200.655. With Lego officially stating the mask is comprised of "pure gold", it would weigh a whopping 1,203.74 pounds! How the dude can hold that on his face is certainly beyond me, and probably Mata Nui himself!
Afterwards, I had a little fun, using this site (http://onlygold.com/m/Prices/YourWeightInGold.asp) to calculate the price it would be in the US Dollar! It turns out it would cost $21,567,016.92, if the site is correct! That's more than I could ever afford!
Well, that was just me having a little fun! I'm no mathematician! Did I screw up somewhere? Just how insane do you think those numbers are? I'd like to hear in the comments!
