The volume of Earth is on the order of 1021 m3. (a) What is this in cubic kilometers (km3) ? (b) What is it in cubic miles (mi3) ? (c) What is it in cubic centimeters (cm3) ?

a) Volume of earth = 1.021 x 10⁻⁶ km³b) Volume of earth = 2.49 x 10⁻⁷ mile³c) Volume of earth = 1.021 x 10⁹ cm³

Step-by-step explanation:

Volume of earth = 1021 m³

a) 1 km = 1000 m

1 m = 10⁻³ km

Volume of earth = 1021 x (10⁻³) ³ = 1.021 x 10⁻⁶ km³

Volume of earth = 1.021 x 10⁻⁶ km³

b) 1 mile = 1600 m

1 m = 6.25 x 10⁻⁴ miles

Volume of earth = 1021 x (6.25 x 10⁻⁴) ³ = 2.49 x 10⁻⁷ mile³

Volume of earth = 2.49 x 10⁻⁷ mile³

c) 1 m = 100 cm

Volume of earth = 1021 x (100) ³ = 1.021 x 10⁹ cm³

Volume of earth = 1.021 x 10⁹ cm³
