The earth is a massive object, and it is hard to comprehend how much it can contain. Many of us have asked ourselves how much can the earth hold? How many basketballs can the earth contain? This article will answer that question and provide some interesting facts about spheres and the earth’s size.

## Earth’s Size

The earth is estimated to be about 12,756 kilometres in diameter. That is roughly the distance from Melbourne, Australia to Vancouver, Canada. Its circumference is about 40,075 kilometres, which is equivalent to the distance from Brisbane to London. The earth is also estimated to have a volume of 1,083,206,916,846 km3.

## How Many Spheres Can Fit in the Earth?

## To answer this question, we must look at the equation of volume of a sphere. The formula is:

## V = 4/3πr3

Where V is the volume of a sphere, π is the constant of 3.14, and r is the radius of a sphere. A basketball is a sphere and its radius is approximately 11.4 cm. To calculate the volume of a basketball, we need to substitute the values into the equation.

## V = 4/3 x 3.14 x 11.4 cm3

## V = 473.6 cm3

Now that we know the volume of a basketball, we can calculate how many basketballs can fit in the earth. To do this, we need to divide the volume of the earth by the volume of a basketball.

## V = 1,083,206,916,846 km3 / 473.6 cm3

## V = 2.29 x 10^16

## This means that the earth can contain 2.29 quadrillion basketballs.

## Interesting Facts About Spheres

The sphere is the most efficient shape in nature, meaning that it can contain the most volume with the least surface area. This is why the earth is a sphere, so it can contain the most mass with the least surface area.

It is also interesting to note that the surface area of a sphere is equal to four times the area of a circle with the same radius. This means that the surface area of the earth is 4 x 3.14 x 6,378,000^2 km2 = 510,072,000,000 km2.

## Conclusion

In conclusion, the earth is an incredibly massive object and it can contain a large amount of basketballs. In fact, it can contain 2.29 quadrillion basketballs. The sphere is the most efficient shape in nature and the surface area of a sphere is equal to four times the area of a circle with the same radius. These facts make it easier to understand why the earth is a sphere and how much it can contain.
