Answer 2

Answer:

2700$kg/m^{3}$

Explanation:

Given:

Density = 2.7 $g/cm^{3}$

To find:

Convert into $kg/m^{3}$

Solution:

Because every substance has a variable density, the weight of the same volume of each substance will vary depending on its density. As a result, each substance has a unique density. The conventional unit of measurement for density is 1 $g/m^{3}$, which is roughly the density of water. However, $kg/m^{3}$ is used as the standard SI unit for density.

Life tubes, like those found on beaches or in swimming pools, are frequently used in applications where density is important. These air-filled tubes are designed to float on water so that swimmers can use them to keep from sinking. Since air is less dense than water, life tubes always float because of this

Given, density = 2.7 $g/cm^{3}$

Now converting the given ,

$kg/cm^{3} =\frac{(27)(1000)}{10}\\ =2700kg/m^{3}$
