Area of a square = S^2
Given area = 441 sq.m
Therefore S^2 = 441 
              s = root 441 = 21 m
hence,the side of the cube is 21 m .Hope it helps and pls mark as the best answer :-)

Area of square = side x side 
=s x s = 441
so it means that we have to find square of 441 and square of 441 is 21 .
so 21 is the side of square
