Question

the volume of the planet saturn is about 827,130,000,000,000 km³. the volume of earth is about 1,083,210,000,000 km³. approximately how many times greater is the volume of saturn than the volume of earth? enter the correct numbers in the boxes to express each quantity in scientific notation. volume of saturn: 827,130,000,000,000 km³ = □×10^□ km³ volume of earth: 1,083,210,000,000 km³ □×10^□ km³

Explanation:

Step1: Convert Saturn's volume to scientific - notation

Move the decimal point 12 places to the left. So, $82713000000000 = 8.2713\times10^{11}$.

Step2: Convert Earth's volume to scientific - notation

Move the decimal point 11 places to the left. So, $1083210000000= 1.08321\times 10^{11}$.

Step3: Find the ratio of Saturn's volume to Earth's volume

$\frac{8.2713\times 10^{11}}{1.08321\times 10^{11}}=\frac{8.2713}{1.08321}\approx7.64$.

Answer:

Volume of Saturn: $8.2713\times 10^{11}$
Volume of Earth: $1.08321\times 10^{11}$
The volume of Saturn is approximately 7.64 times greater than the volume of Earth.
