Answer: I believe that you have to do e^3 to find the volume of a cube.

If you had the side, you would do a^3 (a stands for the side length)

Express the confidence interval (0.432, 0.52 in the form of ±<br> e.
lakkis [162]
For a known standard deviation, the confidence interval for sample size = n is
(x-z \frac{ \sigma }{ \sqrt{n}},x+x \frac{ \sigma }{ \sqrt{n} }  )
where
x =  average
n = sample size
\sigma = stad. deviation
z = contant that reflects confidence interval

Let a = x
Let b = z \frac{ \sigma }{ \sqrt{n} }

From the given information,
a - b = 0.432          (1)
a + b = 0.52           (2)

Add (1) and (2): 2a = 0.952  =>  a = 0.476
Subtract (2) from (1): -2b = -0.088  => b = 0.044

Therefore, the confidence interval may be written as
(0.476 - 0.044, 0.476 + 0.044), or as
(0.476 \pm 0.044)

= 22
Distance traveled by the wheel in one revolution is 22 feet.
Distance traveled in 500 revolutions will be: 500 x 22 = 11,000 feet.</span>
