My name is terry i am 15 my question is how much does our planet earth weigh ???? asked by my dad can you help

thanks terry

Hi Terry,
My reference book says that the volume of the earth is 1.083x10²¹ m³ (3.825x10²² ft³) and the average density is 5.522x10³ kg/m³ (3.447x10² lb/ft³). Thus the mass is 1.083x10²¹ times 5.522 which is 5.980x10²⁴ kg (3.825x10²² times 3.447x10² which is 1.319x10²⁵ lb).
