The <span>perimeter of a face of the new cube is 8 times larger than the previous cube.
</span>Let us say, the side of cube before increase is "a"
Then perimeter of the cube = 12a ,
because the cube has 12 sides.
And perimeter of a face of cube = 4a
Now, the side length is increased by factor of 3 i.e. new side is 3a
Thus, perimeter of new face of the cube = 4*3a = 12a
Therefore, the new perimeter is larger by = 12a - 4a = 8a
15/7 or 2 1/7 (same number but the first one is an improper fraction and the other is a mixed fraction)
Answer:
n/12
Step-by-step explanation:
n(2/24)=n(1/12)
n/1 * 1/12 = n/12
n/12
