Can anyone help me. Not done any maths since 95' at uni. I need to find both density and mass (I know density= mass/volume) but I only have area data. I know volume = area x depth. Any ideas people?

Question

anonymous · Answer

please be more specific ..also there is in fact area density where density = mass/area

unklerhaukus · Answer

If you know the shape and the area you can calculate the volume

anonymous · Answer

unequal (lengths and angles) 6 sided shape. calculated area by dividing up into triangles.

unklerhaukus · Answer

so it is a 2-dimensional shape?

anonymous · Answer

yes

anonymous · Answer

so divide mass by area ..

unklerhaukus · Answer

then it has no volume; and thus no density

unklerhaukus · Answer

i guess i must be area density like Coolsector is saying

anonymous · Answer

ok but i only have the area data not mass.

unklerhaukus · Answer

do you know the material the surface is made of?

anonymous · Answer

plastic

unklerhaukus · Answer

then it has a 3rd dimension

anonymous · Answer

oops! sorry. told you it had been a while.

anonymous · Answer

laptop crashed. so material is plastic and it has a 3rd dimension. what is the next step?

unklerhaukus · Answer

well, how thick is it
