Hello,

We must calculate the volume of water in one hour.

V=15000*PI*0.07²=230,9070600... m^3/h.

Volume of the pond=50*44*.21=462 m^3

Time=462 m^3/ 230.907... m^3/h=2,0008... h≈2 h

It must be noted that the area of the square is calculated through the equation,
                                    A = s²
where A is area and s is the measure of one side of the square. 
To determine the measure of one side of the square, we simply have to get the square root of the area,
                                               s = √A
Substituting the known value,
                                                s = √75 ft² = 5√3 ft ≈ 8.66 cm
Thus, the answer to this question is approximately 8.66 cm.
