Question

If each edge of a cube is increased by 50%, find the percentage increase in the surface area(125%)​

Answer 1

Answer:

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% .
