Well....we can't swear to the "innocent" part....but here goes........
1.66242 x 108 km2 .......there are 10,000,000,000cm^2 in 1 km^2 = 10^10 cm^2 in 1 km^2.......so
1.66242 x 108 x 1010 = 1.66242 x 1018 cm^2
As for the second part, we have
3.940 x 103m .......and there are 100 cm in 1 m = 102 cm
So....
3.940x 103 x 102 = 3.940 x 105 cm
So....putting this all together, we have
1.66242 x 3.940 x 1018 x 105 =
654993480000000000000000 cm^3 =
About 6.6 x 1023 cm^3
P.S. ......check my math, Melody......we Yanks don't deal well with metric units.....!!!
