I see that you've uploaded an image containing three geometry-related word problems, with some multiple-choice options. Let's go through each of them.

### Question 1:
**Problem:**  
A room is 15 feet tall by 88 feet long by 41 feet wide. What is the volume of the room in cubic feet?

**Solution:**  
To find the volume of a rectangular space (like a room), we use the formula for volume:
\[
V = \text{length} \times \text{width} \times \text{height}
\]

Substituting the given values:
\[
V = 88 \, \text{feet} \times 41 \, \text{feet} \times 15 \, \text{feet} = 54,120 \, \text{cubic feet}
\]

So the correct answer is **54,120 cubic feet**.

### Question 2:
**Problem:**  
A pipe is 1 mile long (1 mile = 5280 feet). What is the volume of the pipe if its diameter is 48 inches? (Use \(\pi \approx 3.1416\).)

**Solution:**
This is the volume of a cylinder. The formula for the volume of a cylinder is:
\[
V = \pi \times r^2 \times h
\]
Where:
- \(r\) is the radius of the pipe,
- \(h\) is the height (or length in this case) of the cylinder.

1. The diameter is 48 inches, so the radius is \( \frac{48}{2} = 24 \) inches. Convert the radius to feet:  
\[
24 \, \text{inches} = 2 \, \text{feet}
\]
2. The length of the pipe is 1 mile = 5280 feet.

Now, apply the formula:
\[
V = 3.1416 \times (2)^2 \times 5280 = 3.1416 \times 4 \times 5280 = 66,483.84 \, \text{cubic feet}
\]

So the correct answer is **66,483.84 cubic feet**.

### Question 3:
**Problem:**  
A pipe that is 25 feet long with a diameter of 48 inches has a volume of how many cubic feet?

**Solution:**  
Again, we are dealing with the volume of a cylinder. The formula remains the same:
\[
V = \pi \times r^2 \times h
\]

1. The diameter is 48 inches, so the radius is 24 inches, or 2 feet.
2. The length of the pipe is 25 feet.

Now, apply the formula:
\[
V = 3.1416 \times (2)^2 \times 25 = 3.1416 \times 4 \times 25 = 314.16 \, \text{cubic feet}
\]

So the correct answer is **314.16 cubic feet**.

If you'd like more detailed explanations or have any specific questions, feel free to ask! 

Here are 5 additional questions that expand on this:
1. How do you calculate the surface area of a cylinder instead of its volume?
2. How can the formula for volume be adapted for irregularly shaped rooms?
3. What is the volume of a pipe with a diameter of 36 inches and a length of 2 miles?
4. If the room's dimensions are doubled, how does that affect the volume?
5. How would you convert the volume of the room into gallons?

**Tip:** For cylindrical volumes, always ensure that the diameter is converted to the correct units before calculating.

1. A room is 15 feet tall by 88 feet long by 41 feet wide. What is the volume of the room in cubic feet?
2. A pipe that is 1 mile long has a diameter of 48 inches. What is the volume in cubic feet?
3. A pipe is 25 feet long with a diameter of 48 inches. What is the volume in cubic feet?

Learn how to calculate the volume of a room with dimensions 15 feet tall, 88 feet long, and 41 feet wide. Additionally, discover how to calculate the volume of cylindrical pipes using the formula V = πr²h, with pipes of different lengths and diameters. Suitable for middle school students.
