Answer:
![0.00375\ \text{inches}](https://tex.z-dn.net/?f=0.00375%5C%20%5Ctext%7Binches%7D)
Step-by-step explanation:
Volume of the stack of paper is 140.25 cubic inches
The length and width of the stack will be equal to that of a single sheet of paper so
![l=11\ \text{inches}](https://tex.z-dn.net/?f=l%3D11%5C%20%5Ctext%7Binches%7D)
![w=8.5\ \text{inches}](https://tex.z-dn.net/?f=w%3D8.5%5C%20%5Ctext%7Binches%7D)
Let
be the height of the stack.
Volume of the stack would be
![lwh=140.25\\\Rightarrow h=\dfrac{140.25}{lw}\\\Rightarrow h=\dfrac{140.25}{11\times 8.5}\\\Rightarrow h=1.5\ \text{inches}](https://tex.z-dn.net/?f=lwh%3D140.25%5C%5C%5CRightarrow%20h%3D%5Cdfrac%7B140.25%7D%7Blw%7D%5C%5C%5CRightarrow%20h%3D%5Cdfrac%7B140.25%7D%7B11%5Ctimes%208.5%7D%5C%5C%5CRightarrow%20h%3D1.5%5C%20%5Ctext%7Binches%7D)
So the stack has a height of 1.5 inches. Now there are 400 sheet of paper in the stack.
Thickness of one sheet of paper is given by
![\dfrac{1.5}{400}=0.00375\ \text{inches}](https://tex.z-dn.net/?f=%5Cdfrac%7B1.5%7D%7B400%7D%3D0.00375%5C%20%5Ctext%7Binches%7D)
Hence, the height of each sheet of paper is
