Frisk = 0.9652 meters tall = 77 px
Going to be treating the bottom part of the rock as an elliptical cylinder and the top as an ellipsoid. Its a pretty odd shaped rock with the above perspective.
Ellipsoid volume:
Length 1 = 33 px = (33/77) * 0.9652 = 0.413657143 meters
Length 2 = 26 px = (26/77) * 0.9652 = 0.325911688 meters
Volume of ellipsoid = (4/3) * pi * (0.325911688/2) * (0.325911688/2) * (0.413657143/2) = 0.0230058891 m^3
Elliptical cylinder volume:
Length 1 = 16 px = (16/77) * 0.9652 = 0.200561039 meters
Length 2 = 52 px = (52/77) * 0.9652 = 0.651823377 meters
Height = 13 px = (13/77) * 0.9652 = 0.162955844 meters
Volume of elliptical cylinder = pi * (0.162955844) * (0.651823377/2) * (0.200561039/2) = 0.0167315557 m^3
Total volume = 0.0167315557 + 0.0230058891 = 0.0397374448 m^3
Rock density assumed will be 2600 kg / m^3
Rock mass = 2600 * 0.0397374448 = 103.317356 kg
