The measurement of acre-feet is a unit used primarily to quantify large volumes of water. One acre-foot represents the volume of water that would cover one acre of land to a depth of one foot. To understand why the volume of 43,560 cubic feet is equal to 1 acre-foot, you can visualize the dimensions of an acre.

An acre is defined as 43,560 square feet. Therefore, if you consider a depth of one foot over that area, the total volume would indeed amount to 43,560 cubic feet (1 foot deep x 43,560 square feet = 43,560 cubic feet).

This means that when you have a volume of 43,560 cubic feet, it is equivalent to one acre-foot, as it corresponds exactly to the volume needed to cover an acre to a depth of one foot. Hence, the correct choice is that 43,560 cubic feet is 1 acre.
