Avg height of a tall 2 story is 6-7.6 metres. Ima just wank and call it 7.6 metres tall.

7.6 = 760cm

760/152 = 5cm / px (scale).

Volume = L × W × D

L = 1306 × 5 = 6,530 cm

W = 1245 × 5 = 6225 cm

D = 333 × 5 = 1665 cm

Volume = (6530 × 6225 × 1665) = 67,681,001,250 cm³.

Apply hollowness of 85%

0.15 × 67,681,001,250 = 10,152,150,187.5 cm³.

From this image it seems to be mostly fragmentation and slight violent fragmentation. So I'll use 90% frag 10% Violent frag.

Frag = 8J/cc

Violent frag = 69J/cc

0.9×10,152,150,187.5×8 = 73,095,481,350J.

0.1×10,152,150,187.5×69 = 70,049,836,293.75J.

Total = 143,145,317,643.75 Joules

1 ton of tnt = 4.184×10⁹

Tnt yield = 34.21 tons of tnt (city block level or 8-B)

I left out some stuff in the older calc I had previously made. said calc is here in this link : https://www.reddit.com/r/FeatCalcing/s/e8ZPXv9n88

(check out the prev calc first and to get an idea).

here is the extra stuff :

# extra

Assume 80% wood 20% concrete. Hardest wood I found on vsbw was OAK LIVE.

Vol of wood : 8,045,541,444.9784 cm³

Vol of concrete : 2,011,385,361.2446 cm³

[ Wood values : ]

[Frag = 18.3401 J/cc]

[Violent frag = 19.5811 J/cc]

[Pulverisation = 61.3633 J/cc]

Lowball : 39/400 = 0.0977814995 tons of tnt (wall+ to Small building).

Midball : 70/400 = 0.177059119 tons of tnt (small building).

Highball : 220/400 = 0.55 tons of tnt (Small building to building level).
