A swimming pool is 40 feet long, 20 feet wide, and 8 feet deep. What is the correct way to find the volume of the pool?

To find the volume of the swimming pool, follow these steps:

1. Identify the dimensions of the pool:

   • Length (L) = 40 feet
   • Width (W) = 20 feet
   • Depth (D) = 8 feet

2. Use the formula for the volume of a rectangular prism: $\text{Volume} = \text{Length} \times \text{Width} \times \text{Depth}$

3. Substitute the given dimensions into the formula: $\text{Volume} = 40 \, \text{feet} \times 20 \, \text{feet} \times 8 \, \text{feet}$

4. Perform the multiplication: $\text{Volume} = 40 \times 20 \times 8$

5. Calculate the intermediate step: $40 \times 20 = 800$

6. Multiply the result by the remaining dimension: $800 \times 8 = 6400$

7. Therefore, the volume of the swimming pool is: $6400 \, \text{cubic feet}$
