# If each edge of a cube is increased by 50%, then the percentage increase in its surface area isA. 50%B. 75%C. 100%D. 125%

Let original side be x, on increasing it by 50% i.e.

New side will be x + x = x

Total surface area of a cube = 6(side)2

Original surface area = 6 (x)2

New surface area = 6 (x)2 = 6× x2 = x2

Change in surface area = x2 − 6 (x)2

Taking LCM of 2 and 1 = 2

The percentage increase in its surface area is
