Question

a pamphlet containing 54 sheets of paper was 1.458 cm thick. what was the thickness of sheet of a paper?

Answer 1

We will follow quite simple unitary method to get our answer.

A pamphlet containing 54 sheets of paper is 1.458 cm thick.

Therefore,

Thickness of 54 sheets = 1.458 cm

Now,

Thickness of 1 sheet of paper = 1.458 / 54

On solving further we get,

Thickness of 1 sheet of paper = 0.027 cm

The required answer is 0.027 cm.

We can see that the value is in decimal, so it would be better if we convert it to smaller units.

1 cm = 10 mm
0.027 cm = 0.27 mm

1 mm = 1000 nm
0.27 mm = 270 nm
