Question about Shoto's Ice feat at Stadium

[CNBA3]

I noticed here there is very specific measurements going off the height of characters, I was curious because we know the stadium has a circumference of about 4 kilometers which would give it around 1.27 km in diameter.

and below is the image for quick pixel scaling



shouldn't the mass of the ice be higher with

Stadium Diameter = 1486 px = 1.27 km

upper Ice length = 930.23 px = .8 km

lower Ice length = 931.96 px = .8 km

Average Ice length = (931.96+930.23)/2 = 931.1 px = .8 km

radius Ice = 607.14 px = .52 km / 2 = 0.26 km

Ice height = 0.76 km

Cone Volume = 0.054 km^3 = 5.4e+13 cm^3

Density of Ice = 0.91 g/ml

Density of Water = 1 g/ml

Mass of Ice = 49140000000 kg

Mass of Water as Ice = 54000000000 kg

thoughts?

We don't use that old calculation.

We use this one.

Okay thanks

But based on the size of the Ice wall, what would be the estimated Hollowness percentage?
