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).
