Final answer:
The volume of water in the rectangular pool is approximately 9155 gallons.
Step-by-step explanation:
To find the volume of the rectangular pool, we need to multiply the length, width, and depth of the pool. The given values are: length = 34 feet, width = 12 feet, and depth = 3 feet.
Therefore, the volume of the pool is: 34 feet x 12 feet x 3 feet = 1224 cubic feet.
To convert cubic feet to gallons, we need to multiply the volume by 7.48 (since 1 cubic foot = 7.48 gallons).
So, multiplying 1224 cubic feet by 7.48 gives us 9155.52 gallons.
Therefore, the volume of the water in the rectangular pool is approximately 9155 gallons.
