Sonic is 100 cm tall or 1 meter tall represented by 50 px

Egg Golem cylinder machine part width = 56 px = (56/50) * 1 = 1.12 meters

Machine part width = 47 px = 1.12 meters

Face width = 144 px = (144/47) * 1.12 = 3.4314893617 meters

Face height = 264 px = (264/47) * 1.12 = 6.29106382979 meters

Approximation of head volume via volume of an ellipsoid = (4/3)*pi*(6.29106382979/2)*(3.4314893617/2)*(3.4314893617/2) = 38.7871640992 m^3

Might be easier to just get the final volume to get to this breakdown part but here's what just the head weighs in at to get an idea of the final weight it will be)

Mass breakdown = 50% rock = (38.7871640992/2) * 2600 = 50,423.313329 kg

Mass breakdown = 50% electronic parts

Metals = (38.7871640992/2) *.35 * 8050 * .6 = 32,784.8504548 kg

Plastics = (38.7871640992/2) *.65 * 910 * .6 = 6,882.7822694 kg

Total head mass = 32,784.8504548 + 6,882.7822694 + 50,423.313329 = 90090.9460532 kg

Machine part width = 47 px = 1.12 meters

Arm segment 1 length = 154 px = (154/47) * 1.12 = 3.66978723404 meters

Arm segment 1 length = 124 px = 3.66978723404 meters

Arm segment 1 total height = 200 px = (200/124) * 3.66978723404 = 5.91901166781 meters

Model as cylinders / domes to account for the weird shapes on the ends

Dome radius 1 = 29 px = (29/124) * 3.66978723404 = 0.85825669183 meters

Dome radius 2 = 3.66978723404/2 = 1.83489361702 meters

There's two of these domes on the end of this 1 segment so treat it as a full on ellipsoid.

Domes volume = (4/3)*pi*(1.83489361702)*(1.83489361702)*(0.85825669183) = 12.1039629994 m^3

Cylinder height = 5.91901166781 - 0.85825669183 = 5.06075497598 meters

Cylinder radius = 1.83489361702 meters

Cylinder volume = pi*(1.83489361702^2) * 5.06075497598 = 53.5287329199 m^3

Arm segment total volume = 12.1039629994 + 53.5287329199 = 65.6326959193 m^3

There are two of these entire parts since two arms so multiply final value for this section by 2 to get the volume added to the final number

65.6326959193 * 2 = 131.265391839 m^3

Mass breakdown = 50% rock = (131.265391839/2) * 2600 = 170,645.009391 kg

Mass breakdown = 50% electronic parts

Metals = (131.265391839/2) *.35 * 8050 * .6 = 110952.072452 kg

Plastics = (131.265391839/2) *.65 * 910 * .6 = 23293.0437818 kg

Both segments mass = 23293.0437818 + 110952.072452 = 134,245.116234 kg

Model as a ellipsoid / semi ellipsoid

Model body trunk as a a cylinder(?) / elliptical cylinder(?)

Model stubby legs as cylinders

Density of sections and approximating mass breakdown since the thing is part robot and not totally solid rock

% of rock of whole volume? = 50% estimate for simplicity

Avg Rock density = 2600 kg/m^3

Plastics / electronic parts = ~35% of metal (presumably steel weight at worst and its fictional metal lol, density of steel is 8050 kg/m^3), ~65% plastics (case weight)  910 kg/m^3 or so (cite number), general assumption of robot density is that these parts would be 40% hollow at worst estimate so multiply by .6 for 60% not hollow space with end result.
