Can planet earth be measured by volume and if so can anyone tell me what it is?

Answer 1

The radius of the earth is roughly 4000 miles, or 6,400 km. Therefore we can easily work out the volume using the formula:

V = 4/3 x pi x r^3

where r = 6,400 km or 6.4 x 10^6 m

So V = 1.1 x 10^21 m^3 approximately, or 1100 million million million cubic metres.

Answer 2

Don't worry about all that formula stuff. Who needs to know it down to 10 decimal places? The easiest way to estimate the volume of a sphere is simply to halve the cube.

A ball is just about half the volume of the box it would just fit into.

So, a 10 foot wide sphere is just half the volume of a 10 foot wide cube

= 10 x 10 x 10 divided by 2

= 500 cubic feet

If you want to just get a rough idea of the size of moons, planets, stars etc just apply that rule.

Everyone is so paranoid about exactness when all you need is some impression of size. and whether something is 6000024 cu kms or 6000000 cu kms, what is the difference?

I can show you how to calculate the size and mass of any body, without resorting to high school math.

Answer 3

Volume of a sphere is = 4/3*pi*radius^3
Eventhough the earth is not an exact sphere, this would be a close approximation. Radius of the earth is about 6400 Km or 4000 miles. Then V in cubic Km = 4/3 *3.14159 * 6400^3 ...You can do the calculation on a calculator. Approximately 1.1 x 10^12 Km3.

Answer 4

the volume is easy - we can easily arrive at a radius for the planet, and get the volume from the equation:

V=4/3 X pi X r3

Answer 5

As planets are nearly perfect spheres, a planet's volume can be found from - Planet volume = (pi/6) × (planet diameter)^3.

So the Earths estimated volume is 1.083x10^21 metres cubed

Answer 6

Take the circumference as 25,000 miles. I forget the formula for a sphere (which the Earth isn't - but close enough), but you can look it up.

Answer 7

1.083 207 3×1012 km³


Hope it helps!!
