<h3>Answer: 2 inches</h3>

============================================================

Explanation:

The area of any given sheet of paper is 8.5*11 = 93.5 square inches.

Divide the volume over this area to get the height of the stack

187/(93.5) = 2

The stack is 2 inches tall.

Extra info: The thickness of each piece of paper is 2/500 = 0.004 of an inch which approximates to about 0.1016 mm.

Answer: $9\sqrt{3}$

==========================================================

Explanation:

For any 30-60-90 triangle, the short leg is always half the hypotenuse.

This makes the short leg to be 18/2 = 9 units long.

We then multiply this by $\sqrt{3}$ to get the length of the long leg.

$\text{long leg} = (\text{short leg})*\sqrt{3}\\\text{long leg} =9\sqrt{3}$

Or you could use the pythagorean theorem to solve $x^2+9^2 = 18^2$ and you should get $x = \sqrt{243} = 9\sqrt{3}$
