Question

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?

Answer 1

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. 

Answer 2

Answer: 35 meters

Step-by-step explanation:

Given formula s= square root of SA/6 , where s is the side of square

Surface area of first cube= 480 square meters

Then side of first cube= $\frac{480}{6}=80\ meters$

Now, Surface area of second cube= 270 square meters

Then side of second cube= $\frac{270}{6}=45\ meters$

Difference between their sides=80-45=35 meters

Hence the side of cube with surface area of 480 square meters is 35 meters longer than the cube with the surface area of 270 square meters
