Work = force x distanceWeightWell, the obelisks are roughly cone-shaped. The density of granite is
2.691 g/cc.
Volume of a cone is (1/3) πr
2h.
Cones are ~25 cm tall and ~7.5 wide.
7.5 ÷ 2 = 3.75
3.75 x 3.75 = 14.0625
I'll use 3 for pi.
1/3 x 3 x 14.0625 x 25 = 351.5625 g
351.5625 g is 0.3515625 kg.
ForceTo find force, multiply the weight in kg by
9.81.
0.3515625 x 9.81 = 3.448828125 N
DistanceThe obelisks lift about 15 cm in the air.
EnergyW = fd
3.448828125 x 0.15 = 0.51732421875 J
Total energyAbout 6 large obelisks are lifted. I'll assume that all 6 small ones together equal 1 additional large one.
7 x 0.51732421875 = 3.62126953125 J
3.62126953125 joules is
Supermouse level.
