Check the picture below.

$\bf V=3354~in^3\qquad \qquad 3354=6(w-12)(w+18)
\\\\\\
\cfrac{3354}{6}=w^2+6w-216\implies 559=w^2+6w-216
\\\\\\
0=w^2+6w-775\implies 0=(w+31)(w-25)\implies w=
\begin{cases}
-31\\
\boxed{25}
\end{cases}$

since the width is just a dimension unit, it can't be -31.

what is the length? well, the length is w + 30.

Since we talked about a Man on the Street survey in class today, you decided to do one yourself! You estimate that there is a 0.

Answer:

Therefore, we conclude that the probability is P=0.3456.

Step-by-step explanation:

We know that there is a 0.60 probability that a random student at UMSL has watched Game of Gnomes. We calaculate the probability that 3 of 4 students watched Game of Gnomes.

$p=0.6\\q=1-0.6=0.4\\$

Therefore, we get:

$P=C_3^4\cdot 0.6^3 \cdot 0.4^1\\\\P=4\cdot 0.6^3 \cdot 0.4\\\\P=0.3456$

Therefore, we conclude that the probability is P=0.3456.
