Answer:

The volume of the right rectangular prism is 180m³

The expression that shows how to calculate the volume is as follows

v = 3m * 15m * 4m

Step-by-step explanation:

To calculate the volume of a rectangular prism we have to use the following formula:

v = volume

w = width = 3m

l = length = 4m

h = height = 15m

v = w * h * l

we replace the values that we know

v = 3m * 15m * 4m

v = 180m³

The volume of the right rectangular prism is 180m³

Step-by-step explanation:

Missing information

In this question options are missing.Following are the option

(a) $| x1 -25\ | \leq\ 6$

(b) $| x1 - 6 |\ > 25$

(d) $| x1 +25 |\ > 6$

As mention in the question On the highway, car is said to get 25 miles per gallon

We assume $x1= 25$

also that the value of $x1$ is fluctuate by 6 miles per gallon

$x1 \leq \ 25\ \pm\ 6$

This can be written as

$x1\ -25 \leq \ \pm\ 6$

Therefore

$| x1 -25\ | \leq\ 6$ is the answer
