Feat here. Pixel scaling taken from here.
A character uses her powers to collapse a room to prevent a dude from killing her. This includes destroying about the center half of the floor and the elevator shaft (fyi the reason I'm pixel scaling using the girl (Yukari Hasegawa)'s height in the first picture is because perspective-wise she's about near the center of the room, while if I used her height from the second picture where she's in front of the elevator then she'd be then that'd make the results lower than they should be.
Yukari is 18 in Moonlight Syndrome and noticeably taller than most of the other students, so while the average is 158 cm I'll do 160.
- Pixel Scaling
- Pic 1: 160 / 342 * 895 = 418.713450292 cm (Radius of room, minus the shaft in the middle)
- Pic 2:
- 160 / 342 * 727 = 340.116959064 cm (Visible floor height)
- 160 / 342 * 816 = 381.754385965 cm (Elevator shaft width)
- Pic 3: 381.754385965 / 880 * 71.6 = 31.0609250399 cm (Wall thickness, I'll also be using it for the floor thickness since it seems roughly equal ig)
- Calculations
- Destroyed floor volume:
- Shaft excluded, the destruction seems to reach up to halfway the floor radius, so let's do that.
- 418.713450292 / 2 = 209.356725146
- 381.754385965 / 2 = 190.877192982
- pi x (209.356725146 + 190.877192982)^2 - pi x (190.877192982)^2 = 388781.787154 cm^2 x 31.0609250399 = 12075921.9477 cm^3
- Shaft volume (I'll double the height because we see two floors' worth of shaft being destroyed)
- pi x (190.877192982)^2 - pi x (190.877192982 - 31.0609250399)^2 = 34220.9393253 cm^2
- 34220.9393253 x (340.116959064 x 2) = 23278243.6393 cm^3
- Result: (23278243.6393 + 12075921.9477) x 10 (Fragmentation of reinforced concrete) = 353541655.87 Joules/0.0845 Tons of TNT, Small Building level
- Destroyed floor volume:
