Question

A stack of 1000 sheets of paper is 11.8 cm high. The thickness of each sheet of paper

is______.​

Answer 1

Answer:

Given, stack is 11.8 cm high.

Stack contains paper arranged one above another. This means, height is equal to total thickness of 1000 paper together.

Now, we know,

Number of paper = 1000

Total thickness = 11.8cm

Let thickness of 1 paper be x cm.

So, thickness of 2 papers will be x+x=2x

Thickness of 5 papers will be x+x+x+x+x=5x.

Similarly

Thickness of 1000 papers will be 1000x.

Given, total thickness = 11.8cm

Equating both,

1000x = 11.8 cm

x = 11.8 ÷ 1000 cm = 0.0118cm.

Hence, thickness of one paper = x = 0.0118cm = 0.118mm

Or... Directly you can use another method.

Given,

Thickness of 1000 paper = 11.8cm

So, thickness of 1 paper = 11.8/1000=0.0118cm.

Answer 2

Answer:

0.0118 cm

Step-by-step explanation:

11.8 cm / 1000 = 0.0118 cm
