Question

if the side of a cube is increased by 50%. find out the increment in its total surface area
​

Answer 1

After 50% increase, each edge of the cube becomes 150/100 of the original. Thus, the surface area of the cube becomes (150/100)^2 = 225/100 of the original. Hence, increase in perecentage of surface area = (225-100) = 125%
