We know, surface area of cube = 6a²
So, side length of 1st cube = a² = 81/6
a = 3.67
Side length of 2nd cube = a² = 144/6
a = 4.90
Now, volume of cube = a³
Volume of 1st cube = 3.67³ = 49.43
Volume of 2nd cube = 4.90³ = 117.64
So, Ratio = 49.43 / 117.64 = 1/2.38
In short, Your Answer would be: 1: 2.38
Hope this helps!

For this case we have the following function:
f (t) = -16t2 + 32t + 384
By definition we have to:
The average rate of change:
AVR = (f (t2) - f (t1)) / (t2 - t1)
Where,
For t1 = 4
f (4) = -16 * (4) ^ 2 + 32 * (4) + 384
f (4) = 256
For t2 = 6
f (6) = -16 * (6) ^ 2 + 32 * (6) + 384
f (6) = 0
Substituting values we have:
AVR = (0 - 256) / (6 - 4)
AVR = -128
Answer:
The average rate of change of f (t) from t = 4 seconds to t = 6 seconds is -128 feet per second.
