Convert Area Density to Volumetric Mass Density
By James Williams
If the area density is 5.5kg/m², then what is its volumetric density in kg/m³?;)
The thickness is 1/8 inch.
I'm not getting the answer I'm being told is the correct answer and going nuts here;)
What is the formula here?
Thank you.

$\begingroup$A first step is converting the ${1\over8}$ inch to a metric quantity. You have obtained $0.0031$ m. It follows that your one square meter sheet is in reality a box of volume
$V=1$ m${}^2 \times0.0031$ m = $0.0031$ m${}^3\ $.
Since this "box" weighs $5.5$ kg the volumetric density $\rho$ of the material is given by
$\rho={\displaystyle{5.5 \>{\rm kg}\over0.031\>{\rm m}^3}}=1774.2\>$ kg/m${}^3$.
That's my last word on this matter.
