The formula s = square root of SA/6 gives the length of the side, s, of a cube with a surface area, SA. How much longer is the side of a cube with a surface area of 480 square meters than a cube with the surface area of 270 square meters?

To determine the answer to this item, we just have to calculate for the length of the sides of the cube.

Cube 1: Side = sqrt (480/6) = 4 sqrt (5)

Cube 2: Side = sqrt (270/6) = 3 sqrt (5)

We divide both sides to get the answer which is equal to 4/3.
