When gorilla is standing and keeping that log straight on the ground there is a way to calculate approximate weight. Gorillas are usually about 170 cm when standing, if big one 180 cm. So that log is most probably about 2 meters and then diameter about 30 cm. So volume of that log is approximately 0,14 cubic meter but let´s say 0,15.

That is also obviously quite dry wood when looking at it. When we know now approximate volume it is quite easy to look at possible weight. Spruce 65,5-68,5 kg. Birch would be 91-95 kg. Pine 73-76 kg.

If someone can give estimation about wood, then it is possible to give approximate weight for any log if there is some way to get approximate measurements :)

Same thing with rocks/stones, some estimations which will be quite close can be calculated.

If you say that volume is 0,14 cubic meter wood, with a density of 0,8, the weight would be 1000 X 0,14 x0,8 = 112 kilos
Density of 0,9 =>  weight = 126 kilos
Density of 0,7 => weigth = 98 kilos

Because very rare sorts of wood don't float on the water, I don't suppose that the density could be > 1. Even in this extreme case (density = 1), the weigth would be 140 kilos.

I used calculator which take note how dry wood is. I calculated weight based on quite dry wood, humidity about 20%. Fresh just chopped tree is naturally much heavier. I think, that you calculated weight of fresh tree. Reply
