Question

I will give medal

Answer 1

Paper is sold in packets labelled \[80g/m^2\] This means that a sheet of paper of area \[10000cm^2\]has a mass of 80g.

The thickness of each sheet is 0.11mm.

What is the density of the paper?

Answer 2

I know that density=mass/volume but they have not given volume of sheet

Answer 3

Answer 4

i think that 80g/m^2 is density but they have mistaken it by not writing m^3

Answer 5

Yes that's missing. Maybe it's assumed that they're talking about standard form papers like A4.

Answer 6

Oh wait !

Answer 7

please have a look here...

Answer 8

You have the area, to get the volume just multiply by the thickness.

Answer 9

yeah, you must have the thickness of the paper here... @sheelo_mughal

Answer 10

options are \[1)0.073g/cm^3\]
\[2)0.088g/cm^3\]
\[3)0.73g/cm^3\]
\[4)0.88g/cm^3\]

Answer 11

Which one do you think is right ?

Answer 12

Volume = 10000 * 0.011 (cm^3)
Density = mass / volume

Answer 13

i got it
