Crank

First, we get the standard error of the mean using
σm = σ / √N
= 5 / √100
= 0.5

Next, we subtract and add 1.96 standard deviations from the mean (since the confidence interval is 95%). So,
8 ±1.96 (0.5)
= 8 <span>± 0.98

A prism with square bases is just a square prism.

The volume of a rectangular prism is equal to its width times its length times its height. Since the base is a square, we can just say it's equal to the base squared times the height. Let's set up a formula, plug and chug.

$V = b^2h \\ 5880 = 30b^2 \\ 196 = b^2 \\ \sqrt{196} = b \\ \boxed{14 = b}$
