What will be the percentage increase in the area of the cube's surface if each of the cube's edges grows by 50%?
Choose the most appropriate option:
A) 125% B) 150% C) 100% D) 90% E) 85%
The question is very easy. My logic is the following:   125% surface = 6*a^2   125%fter 50% increase 125% surface = 6* ((1.5a)^2) = 6*2.25*a^2   The increase in the surface area = (6*2.25*a^2 - 6*a^2)/6*a^2 = (6*a^2(2.25-1))/(6*a^2) = 2.25-1=
