Okay, firstly, let's list some multiples of 5 and 8.
5 : 5, 10, 15, 20, 35, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90
8 : 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120
I've emboldened two of the multiples of 5 and 8 that are the exact same in both lists. They are 40 and 80. And the lesser multiple out of the two of them is 40. So we'll be using the number 40 to simplify
.
So let's divide, the numerator before the denominator. 120 ÷ 40 is 3. And 160 ÷ 40 = 4. Simplified, using the numbers we just found, our final answer is

The surface area (SA) of a cube can be written as:
SA = 6s²
From here we can write, the length of the side s as:
For cube with surface area of 1200 square inches, the side length will be:
inches
For cube with surface area 768 square inches, the side length will be:
inches
The difference in side lengths of two cubes will be:
Rounding to nearest tenth of an integer, the difference between the side lengths of two cubes will be 2.8 inches.
