Answer:the new surface will be 9 times the old surface area
Explanation:
Let's find the current surface area of the cube.
A = 6a^2
A = 6
Now let's find the surface area of the cube when tripled.
A = 6(3^2)
A = 54
54/6 = 9
So, the answer should be the new surface area will be 9 times the old surface area.
