Answer:

What is the scienctific name of particles which make up matter?

Answer 2

Answer:

125

Step-by-step explanation:

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%
