The volume of a sphere, such as a planet, can be calculated using the formula V = 4/3πr³, where V represents the volume and r represents the radius of the sphere. This formula is commonly used in mathematics and physics to calculate the volume of three-dimensional objects.
B. Applying the formula to Earth’s measurements
Using the measurements of Earth’s radius and circumference, we can calculate its volume. Earth has an average radius of approximately 6,371 kilometers (3,959 miles) and a circumference of approximately 40,075 kilometers (24,901 miles).
Plugging these values into the formula, we can calculate Earth’s volume as follows:
V = 4/3 * π * (6,371 km)³
≈ 4/3 * 3.1416 * (6,371 km)³
≈ 4/3 * 3.1416 * 258,984,045,156 km³
≈ 1.086 × 10^12 km³
Therefore, the volume of Earth is approximately 1.086 × 10^12 cubic kilometers.
Calculating the volume of a planet allows us to better understand its size and capacity. In this case, knowing the volume of Earth will help us determine how many Mars can fit within our planet.
Estimating the volume of Mars will allow us to make a direct comparison and answer the intriguing question of how many Mars can fit in Earth.

Formula for mass calculation
To convert volume to mass, we can use the formula:
Mass = Density × Volume
Applying the formula
Considering the volume values we calculated in the previous sections, we can substitute those values into the formula to find the masses of Earth and Mars.
For Earth:
Mass of Earth = Density of Earth × Volume of Earth
Substituting the values:
Mass of Earth = 5,515 kg/m³ × 1.08321 × 10²¹ m³
Simplifying the calculation, we find that the mass of Earth is approximately 5.97 × 10²⁴ kilograms.
Similarly, for Mars:
Mass of Mars = Density of Mars × Volume of Mars
Substituting the values:
Mass of Mars = 3,933 kg/m³ × 1.6318 × 10²⁰ m³
The mass of Mars is then approximately 6.42 × 10²³ kilograms.
Implications of the results
Comparing the mass of Earth to that of Mars, we find that Earth is approximately 10 times more massive than Mars. This sizable difference in mass is due to Earth’s larger volume and higher density. The implications of this stark contrast are significant.
The greater mass of Earth has profound implications for its gravitational pull, atmospheric composition, and geological processes. Earth’s stronger gravity allows it to hold onto a denser atmosphere, which in turn supports a wide variety of life forms. Additionally, Earth’s higher mass leads to more intense volcanic activity and a more robust magnetic field.
On the other hand, Mars’ lower mass has resulted in a weaker gravitational pull, a thinner atmosphere, and less volcanic activity. These factors, along with the absence of a strong magnetic field, contribute to the harsh and inhospitable conditions found on Mars.
Understanding the mass differences between Earth and Mars helps us appreciate the uniqueness and preciousness of our home planet. It also serves as a reminder of the challenges and limitations we might face in our exploration and colonization efforts on Mars.
