Earth's mass is 6.6 sextillion tons (5.9722 x 1024 kilograms). It volume is about 260 billion cubic miles (1 trillion cubic kilometers). The total surface area of Earth is about 197 million square miles (510 million square km). About 71 percent is covered by water and 29 percent by land
Density is a material's mass divided by a unit volume, generally expressed as g/cm3 so we need to multiply by 1000 to convert kg to g. This is easy with scientific notation: the Earth's mass is 5.97 x 1027 g. Now recall that we determined a few pages back that the volume of Earth is about 1.08575832413598 x 1027 cm3.
