Lubbock is 165 cm tall
Lubbock’s height = 1.65m (137 px)
Crater’s diameter = 5.68467152m (472 px)
Crater’s depth = 0.818978101m (68 px) I used the measure stick to scale a bit above the portion of his leg that is actually standing in crater because the crater is clearly deeper than where he’s standing as he’s standing on the edge of it and the edge is rather steep.
Shaping this into a cone I’d get 6.9287 m^3
No idea what value to use for this so I’ll just have 3 ends.(Pulverization seems the most reasonable imo)
