Answer 1

Assume the height of the box is x.

5 reams of paper have 5 x 500 = 2500 sheets of paper.

This means that each sheet of paper has a thickness of x/2500.

Two sheets of paper have a thickness of 2 times x/2500.

Simplifying the fraction:

`2\cdot(x)/(2500)=(x)/(1250)`

Two sheets of paper have a thickness of 1/1250th of the height of the box.

Assume the height is x = 20 cm, then two sheets are 20/1250 = 0.016 cm thick.
