A large rectangular swimming pool is 1,000 feet long, 100 feet wide, and 10 feet deep. The pool is filled to the top with water.

What is the area of the surface of the water in the pool?

To find the area of the surface of the water in the pool, we can multiply the length and width of the pool. The surface area is equal to length multiplied by width:

1000 feet * 100 feet = 100,000 square feet.
Therefore, the surface area of the water in the pool is 100,000 square feet.
