Question

A ping pong ball has a volume of approximately 3.4 cm3 ; the Earth has a volume of approximately 1.1 x 1027 cm3. Using scientific notation, calculate approximately how many ping pong balls would fit inside the Earth. Show and explain your work, rounding to the nearest tenth; answer in a complete sentence.

Answer 1

Answer

Find out the how many ping pong balls would fit inside the Earth.

To prove

Let us assume that the number of ping pong  would fit inside the Earth be x.

As given

A ping pong ball has a volume of approximately 3.4 cm³.

The Earth has a volume of approximately $1.1\times 10^{27}$ cm³ .

Than the equation becomes

$3.4\times x = 1.1\times 10^{27}$

$x = \frac{1.1\times 10^{27}}{3.4}$

$x = 3.2\times 10^{26}$ (approx)

Therefore in $3.2\times 10^{26}$ (approx)  ping pong balls would fit inside the Earth.
