Earth's volume is more than ten times as great as Mars's volume? TRUE OR FALSE

False

Explanation:

A planet's volume tells you the size of the planet.

The primary composition of a planet is what the planet is made mainly of. In our solar system, planets are made mainly of rock, gas, or ice.

Scientific notation

The volume of a planet is a very large quantity. Large quantities such as this are often written in scientific notation.

For example, the volume of Jupiter is 1,430,000,000,000,000 km3. In scientific notation, Jupiter's volume is written as 1.43 x 1015 km3.

To compare two numbers written in scientific notation, first compare their exponents. The bigger the exponent is, the bigger the number is. For example:

1.43 x 1015 is larger than 1.43 x 1012

If their exponents are equal, compare the first numbers. For example:

1.43 x 1015 is larger than 1.25 x 1015

To multiply a number written in scientific notation by a power of 10, write the multiple of 10 as 10 raised to an exponent. Then, add the exponents. For example:

1.43 x 10^15 * 1000

= 1.43 x 10^15 * 10^3

= 1.43 x 10^15+^3

= 1.43 x 10^18
