Okay, I’m a little embarassed that my google-fu isn’t up to the task of finding this out. Can anyone lend me a hand? I’m looking to find what a life-sized marble or granite statue of an adult male (human) would weigh. Any help would be appreciated.
Granite has an average density of about 2.75 g/cc; marble about 2.6 g/cc, and people about 1 g/cc.
A 200 Lb person would thus weigh 550 pounds when rendered in granite, or 520 pounds in marble.
Apparently body volume in adult males can be estimated using the formula V = -4.7573 + 1.0153 W. Where W = weight in kg and V = volume in litres.
So assume average weight male = 182lbs or 82.5kg roughly
V = -4.7573 + (1.0153x82.5) = -4.7573 + 83.76225 = 79.00495 litres
Given that we can’t be too dissimilar to the weight of water and water weighs 1kg per litre that would seem about right to me so lets go with that.
Now marble weighs 2563 kg/cu. m and Granite 2691 kg/cu.m. 79.00495 litres is 0.07900495cu.m.
Therefore your Marble statue weighs 202.48kg (445lbs) and Granite 212.6kg (467lbs).
And on preview, damn you Squink!
Assuming that it’s not a nude statue, it might weigh significantly more depending on what clothes they were depicted as wearing, since it’s air between clothing and skin in the real person (weighing nothing at all on the scales), but it’s solid stone in a statue. So if they are wearing a large cloak ore overcoat, that would add a lot of mass.
Semi-related, DC Comics’ “The Metal Men” would have roughly the following weights, using a human of similar build as a guide:
Gold (roughly the same build as a tall slim 170lb man): 3300lbs
Lead (short tubby 240lb man): 2900lbs
Platinum (medium build moderately tall 125lb woman): 2700lbs
Mercury (tall slim 160lb man): 2200lbs
Iron (tall muscular 250lb man): 2000lbs
Tin (small 130lb man): 1000lbs
When Doc Magnus cradles an injured Platinum (“Tina”) in his arms, he must be gritting his teeth in effort.
