What is the volume of a square acre?

Answer 1

There's no such thing as a "square acre".

An "acre" is an area, a flat surface, a figure that could be drawn on paper

if you could find a paper big enough. It has no volume, until you build up

the sides so that it can hold water.

A volume that sits on an acre of land and has built up sides so that it can

hold water has a volume of 43,560 cubic feet for every one foot deep.

Answer 2

An acre is a unit of area, typically measuring 43,560 square feet. It does not have a volume as it is a 2-dimensional measurement.
