Planet Earth

What is the weight of the planet Earth, if its average density is ρ = 2.5 g/cm ^ 3?

Correct result:

m =  2.70801729212E+21 t

Solution:

ρ=2.5 g/cm3 ρ1=ρ kg/m3=ρ 1000  kg/m3=2.5 1000  kg/m3=2500 kg/m3  R=6371 km m=6371 1000  m=6371000 m   V=43 π R3=43 3.1416 63710003=1.083206916851021 m3  m1=ρ1 V=2500 1.083206916851021=2.708017292121024 kg  m=m1 t=m1/1000  t=2.708017292121024/1000  t=2.708017292121021 t=2.708017292121021 t
