1 acre = 43,560 square feet
If the sides are straight (the area of the bottom is the same
as the area of the top and of every cut in between), then
Volume = (area) x (depth) = 43,560 x 20 = 871,200 cubic feet = 6,517,028.6 gallons (rounded)
A sixty-acre lake averaging 20 feet deep has a volume of 391,021,200 gallons.
I'm assuming you mean acre feet of water. If that is the case, then there are 325,850.58 gallons in one acre foot of water or 4,887,758.7 gallons of water in 15 acre feet of water.
Six acre-feet of water is about 1,955,109 US gallons.
One acre-foot is about 325,851 US gallons.
1,135 acre-feet of water equates to 369,841,371 US gallons.
22 acre-feet equates to 7,169,000 gallons of water.
One acre of wetlands can store up to 360,000 gallons of water One acre of wetlands can store up to 360,000 gallons of water
Each acre-foot equates to 325,851 US gallons of water so multiply acre-feet by 325,851 to determine fluid gallons.
It depends on the depth of the water. Assuming the water in one inch deep, there would be about 13,577 gallons of water in the half acre.
8 billion gallons is 24,551 acre-feet.
Multiply acre-ft by 325,900 to get gallons. So your answer would be about 138 billion gallons, more precisely 1.379 x 1011 gallons. We know that 1 acre foot = 325 851.427 US gallons. We need to find the number of gallons of water in 423035 acre feet. 1 acre foot = 325 851.427 US gallons. So, 423035 = 325 851.427 * 423035 US gallons = 137846558420.945 US gallons. Approximately 1.37846559 × 1011 US gallons of water are there in 423035 acre feet.
