What will be the percentage increase in the area of the cube's surface if each of the cube's edges grows by 20%?  Choose the most appropriate option:	A) 33%	B) 44%	C) 55%	D) 56%	E) 73%
The question is very easy. My logic is the following:   A surface = 6*a^2   After 20% increase A surface = 6* ((1.2a)^2) = 6*1.44*a^2   The increase in the surface area = (6*1.44*a^2 - 6*a^2)/6*a^2 = (6*a^2(1.44-1))/(6*a^2) = 1.44-1=
