Question

if the length of each edge of a cube inceases by 50%, what is the percentage increase in the total surface area of the cube
​

Answer 1

Step-by-step explanation:

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% .
