Homer lifts his family and this rock[]
So first this rock size
Homer 338 px =182.88 cm
Rock diameter 120 px = 64.9278106508 cm
Divide that by two for radius and we get 32.4639053254 cm
Equation for volume of a sphere is 4/3*π*32.4639053254^3 = 143314.752755 cc
Density of stone is 1.602 gram per cubic centimeter so 1.602 * 143314.752755 = 229,590.233914 grams or 229.590233914 kg Peak Human
But that’s not it since in this scene he lifts his entire family as the rock is lifted in the air from him just running fast
Marge is 4ft 6 average weight for a woman her height is 31.7 kg
For the kid’s i’ll go by their age for their weight since their height is very inconsistent across several sources
Lisa is 8 so she weights 25.8 kg
Bart is 10 and he weights 31.9 kg
So 229.590233914 + 31.9 + 25.8 + 31.7= 318.990233914 kg Peak Human so no buff :(
Homer lifts a larger rock[]
Homer lifts a larger rock in helter shelter intending to use it to destroy
Homer 229 px = 182.88 cm
Rock diameter 231 px = 184.47720524 cm
Divided by two we get 92.2386026201 cm
Using volume for a sphere
4/3*π*92.2386026201^3=3,287,204.73723
Density of stone is 1.602 g/cc
1.602 * 3,287,204.73723 = 5266101.98904 grams or 5266.10198904 kg Class 10 neato
