Question

If each side of cube is increased by 50%,find the %increase in its surface area

Answer 1

$\huge\boxed{Answer}$

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% .

Answer 2

Answer:

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% .
