Water for irrigation is measured in acre-feet. One acre-foot is the volume of water that would cover one acre of land to a depth of one foot. How many acre-feet of water would it take to cover 600 acres to a depth of one inch?

600 ac in / (12 /in/ft) = 50 ac ft

To calculate the number of acre-feet of water required to cover 600 acres to a depth of one inch, you can follow these steps:

1. Determine the volume of water needed to cover one acre to a depth of one foot:
- One acre-foot is the volume of water that would cover one acre of land to a depth of one foot.
- So, the volume of water needed to cover one acre to a depth of one foot is one acre-foot.

2. Convert the depth from inches to feet:
- Since the depth is given in one inch, you need to convert it to feet.
- There are 12 inches in a foot, so dividing one inch by 12 will give you the depth in feet.
- In this case, one inch is equal to 1/12 feet.

3. Calculate the volume of water needed to cover 600 acres to a depth of one inch:
- Multiply the volume of water needed to cover one acre to a depth of one foot (from step 1) by the depth converted to feet (from step 2).
- Multiply one acre-foot by 1/12 feet to get the volume of water needed to cover one acre to a depth of one inch.
- Finally, multiply this value by the number of acres (600) to get the total volume of water needed.

So, to cover 600 acres to a depth of one inch, it would take:
1 acre-foot * (1/12 feet) * 600 acres = 50 acre-feet of water.
