A solid aluminum cube has sides each of length L . A second cube of the same material has sides four times the length of the first cube; i. e., 4 L . Compared to the first cube, the total surface area of the second cube is

Compared to the first cube, the total surface are of the second cube is 16 times larger.

Step-by-step explanation:

The first cube has L*L*6=6L²

The second cube has 4L*4L*6=14L²*6=84L²

Compared to the first cube, the total surface are of the second cube is 16 times larger.  (6*16=84)
