Explanation:
<h2>Given:</h2>
m = 49.9 kg
ρ = 270 kg/m³
<h2>Required:</h2>
volume
<h2>Equation:</h2>

where: ρ - density
m - mass
v - volume
<h2>Solution:</h2>
Substitute the value of ρ and m





<h2>Final Answer:</h2><h3><u>Volume is 0.1848 m³</u></h3>
The density is about 3.88. You just have to divide the mass and the volume. You can check this on a calculator, too. Hope this helped
