Let $x$ represent the length of each side of the square, then:  $x^{4} = 1296 \implies x^{2} = \sqrt{1296} = 36$.  Hence $x = \sqrt{36} = 6$ and $4x = 4\times 6 = 24$. 
The product of all $$4$$ sides of a square is $$1296$$. The sum of all $$4$$ sides of the square is． 
Options:
A. $$24$$ 
B. $$36$$ 
C. $$48$$ 
D. $$72$$
