A swimming pool is 35 feet long, 25 feet wide, and 6 feet deep. What is the correct way to find the area of the pool?

To find the area of the swimming pool, you need to determine which surface you are interested in. Since the pool is a three-dimensional object, it has multiple surfaces. However, if we are looking for the surface area of the bottom of the pool (the floor), we can proceed as follows:

1. Identify the dimensions of the bottom surface of the pool. The length is 35 feet and the width is 25 feet.
2. Use the formula for the area of a rectangle, which is: $\text{Area} = \text{Length} \times \text{Width}$
3. Substitute the given values into the formula: $\text{Area} = 35 \, \text{feet} \times 25 \, \text{feet}$
4. Perform the multiplication: $\text{Area} = 875 \, \text{square feet}$

Therefore, the area of the bottom surface of the swimming pool is 875 square feet.
