Answer:

a) Volume of earth = 1.021 x 10⁻⁶ km³

b) Volume of earth = 2.49 x 10⁻⁷ mile³

c) 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

a) Volume of earth = 1.021 x 10⁻⁶ km³

b) Volume of earth = 2.49 x 10⁻⁷ mile³

c) Volume of earth = 1.021 x 10⁹ cm³

  • The calculation is as follows:

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
