An acre is a two dimensional measure of area. You cannot have square acres since that would represent a measure of "area" in a hyperspace of 4 dimensions. And a square acre foot would be in 5 dimensional [linear] hyperspace!
It is a measure of volume usually used when measuring the water in a lake or large reservoir. An acre foot is the amount of water that it would take to cover one acre of land with one foot of water.
There is no such thing as a square acre. The unit of area is simply called acre. An acre has 43,560 square feet, so you simply multiply 5 x 43,650 x 4. Answer is in cubic feet. =======================================> 20 acre-feet
20 acres = 0.03125 square miles.
The answer will depend on how deep the lake is!
A 1000 acre lake that is 7 feet deep (uniformly) will have 7000 acre feet of water in it. An acre foot is an acre of water one foot deep, and the unit is used to measure reservoir water capacity. The conversion factor is that one acre foot equals about 325,851.5 gallons. The lake in question is holding 7000 times 325,851.5 gallons of water.
Lake Eufaula has a shoreline distance of 600 miles (965.6 km) and a water volume of 2,099,000 acre feet.
528,957 acre-ft of water
Lake Brownwood is 150 acre with a water depth of 70 feet.
Lake Pleasant, Arizona has 653062 acre-feet which is 212,801,184.619.474 gallons.
The lake has 365 miles of shoreline and is the third biggest lake in California and has a water capacity of 4,552,000 acre feet
Since 'circumference' refers to a circle, if the lake is a circle with an area of six acres, the circumference would be: 2,563 feet.
1 acre = 43,560 square feetIf the sides are straight (the area of the bottom is the sameas the area of the top and of every cut in between), thenVolume = (area) x (depth) = 43,560 x 20 = 871,200 cubic feet = 6,517,028.6 gallons (rounded)
