Answer:
Step-by-step explanation:
V = l * w * h
27000ft3 = (2w) * w * 10ft
27000ft3 = 2w^2 * 10ft
2700 = 2w^2
1350 = w^2
W = 36.74

Answer: the fraction 1/9</h3>
It is approximately equal to 0.1111
=================================
To get this answer, we use the rule
![x^{-k} = \frac{1}{x^k}](https://tex.z-dn.net/?f=x%5E%7B-k%7D%20%3D%20%5Cfrac%7B1%7D%7Bx%5Ek%7D)
The negative exponent tells us to apply the reciprocal to get the exponent to be positive.
So,
![(-3)^{-2} = \frac{1}{(-3)^2}\\\\(-3)^{-2} = \frac{1}{9}](https://tex.z-dn.net/?f=%28-3%29%5E%7B-2%7D%20%3D%20%5Cfrac%7B1%7D%7B%28-3%29%5E2%7D%5C%5C%5C%5C%28-3%29%5E%7B-2%7D%20%3D%20%5Cfrac%7B1%7D%7B9%7D)
Squaring -3 means you square the negative as well
![(-3)^2 = (-3)*(-3) = 9](https://tex.z-dn.net/?f=%28-3%29%5E2%20%3D%20%28-3%29%2A%28-3%29%20%3D%209)
