Given that:
- The box contains 5 reams of paper.
- One ream of paper is 500 sheets of paper.
Let be "x" the thickness of a ream of paper.
Knowing the number of sheets that one ream of paper contains, you can determine that the thickness of one sheet of paper is:
![(x)/(500)](https://img.qammunity.org/2023/formulas/mathematics/college/w4zq8q5dq44titi4zn0fqc2u6e794i4bub.png)
In this case, you need to estimate the thickness of 2 sheets of paper. Therefore, assuming that all the sheets have the same thickness, you need to multiply the thickness of one sheet of paper by 2:
![2\cdot(x)/(500)](https://img.qammunity.org/2023/formulas/mathematics/college/8p5mf0z0jrjer37q2ejwbxb8h91hj4vhyq.png)
Hence, the answer is: You could divide the thickness of one ream of paper by the number of sheets of paper a ream of paper has, in order to find the thickness of one sheet of paper, and then multiply the result by 2.
