An A4 writing pad is marked 60 g/m2 meaning that a square metre of the paper has a mass of 60 gram.?

Question

Estimate the thickness of the paper in mm?

Answer 1

not enough information

Answer 2

An A4 writing pad is marked 60 g/m2 meaning that a square metre of the paper has a mass of 60 gram.?

Answer: Yes

Estimate the thickness of the paper in mm?

Answer: 0.08 mm

Answer 3

You give the area of the paper and mass of the paper. That's not enough info to do anything. You need to be thinking in terms of density dude. If it is low density paper, it will be thicker - and vice versa.

You can estimate it by using the density of regular A4 paper pad - so check the manufacturer's specs.

Answer 4

a sq metre of the a4, about 12/14 sheets will weigh 60 grams

Answer 5

Not enough information. All you know is that for a given size of sheet you have a given weight. In order to acertain the thickness you would also need to know the density of the paper.

Answer 6

The density of paper is 1.20gcm^-3 and so by converting the mass of a square metre sized sheet into gcm^-3 we can divide this density into it to get a value for the thickness.
60g/m^2=0.0006gcm^-2
=> thickness of paper is 0.0006gcm^-2/1.20gcm^-3=0.0005cm
=0.5micrometres.

Answer 7

This doesn't help with the theory, but my 90 gsm printer paper measures 0.12 mm, your example is 60 gsm, 2/3 rd's of mine, therefore - 0.12 * .6666 R = 0.8 mm, this should be right for paper of the same density and type, hope it helps.

Answer 8

More info is probably needed but, here's my shot at it: -

1 A4 sheet = 21 cm x 29.7 cm = 623.7 cm² (0.6237 m²)

Weight of 1 m² = 60 g

Weight of A4 = 3.7422 g

Volume = w x l x h = 21 cm x 29.7 cm x T (thickness)

Weight = 3.7422 g

T = 3.7422 ÷ 623.7 = 0.006 cm = 0.06 mm

Answer 9

You cannot estimate the thickness from the wieght and surface area. If the paper is very dense it will be thinner than an equivalent not so dense one.
