Question

The amount of water in reservoirs is often measured in acre-ft. one acre-ft is a volume that covers an area of one acre to a depth of one foot. an acre is an area of 43 560 ft2. find the volume in si units of a reservoir containing 20.0 acre-ft of water.

Answer 1

convert the volume of water from acre - ft to ft³

v = (20.00acre ft)43,560ft³/1 arc ft

  = 8,71,200

   = 8.71 x 10⁶ ft³

  here, v is the volume of water

Answer 2

Answer:

871,200 acre-ft of water

Explanation:

Volume= 1 acre-ft=43,560ft^2

Volume= 20acre-ft=?

Volume= 20 acre-ft × 43560ft^2

Volume = 817,200 acre-ft^3
