60\5= 12

The side of a cube with a surface area of 1,200 is 72 inches longer than a cube with the surface area of 768 square inches.

You can substitute each given number for SA in the formula s = SA/6.

s = 1,200/6
s = 200

s = 768/6
s = 128

Then, to find how much longer the side of a cube with a surface area of 1,200 than a cube with the surface area of 768 square inches, subtract the length of the side of a cube with the surface area of 768 square inches (128 inches) from the length of the side of a cube with a surface area of 1,200 square inches (200 inches).

200 - 128 = 72

The side of a cube with a surface area of 1,200 is 72 inches longer than a cube with the surface area of 768 square inches.
