How to find density? (Changing units)

82 Views Asked by At

I have a 10 kg/m^2 weight load for a steel sheet and I would like to calculate the density of the steel sheet.Is it possible to calculate the density of the steel sheet using the value of 10 kg/m^2 weight load?

I have tried calculating value for density by multiplying by the area (m^2) of the steel sheet, then dividing by the volume of the steel sheet which gives units of kg/m^3. However when I change the size of the area or volume for example, my density value will change? Shouldn't the density be constant for a material.

How can I calculate the density from 10 kg/^2? (If it is possible)

Thanks in advance.

You need the thickness of the sheet, which will give you the factor of length that you need. Yes, the density should be constant. Typical densities of steel range from $7750$ to $8050$ kg/m$^3$, which says your sheet is about $\frac {10}{7900}$meters thick.
