Question

the density of the earth is greater than the density of an equal volume of water by _____.
1½ times
3½ times
5½ times
7½ times

Explanation:

Step1: Recall density values

The average density of the Earth is about 5500 kg/m³ and the density of water is 1000 kg/m³.

Step2: Calculate the ratio

$\frac{5500}{1000}= 5.5$ which means the density of the Earth is 5.5 or 5½ times greater than the density of an equal - volume of water.

Answer:

5½ times
