if each edge of a cube is increased by 50 % , find the percentage increase in its surface area
let the edge = a cm so increase by 50 % = = total surface area of original cube = tsa of new cube = = = increase in area = = increase % = = 125 % answer : a
multiply(divide(subtract(multiply(power(divide(const_3, const_2), const_2), multiply(const_3, const_2)), multiply(const_3, const_2)), multiply(const_3, const_2)), const_100)
