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 % = a + a/2 = 3a/2
Total surface Area of original cube = 6a2
TSA of new cube = 63a22 =69a24= 13.5a2
Increase in area = 13.5a2-6a2 =7.5a2
7.5a2 Increase % =7.5a26a2×100 = 125%
