The person above me is right!! I kinda got confused because i thought it was asking what sea level is the diver now BUT its asking for the elevation, so you need to subtract.
By induction:
It's true for

, since

clearly contains a factor of 3.
Suppose it's true for

, that

is divisible by 3. Then

where

is an integer. This reduces to

and both terms are clearly multiples of 3. We know that

is an integer since we had set

previously, which implies

is a multiple of

. So the statement is true.
Volume of a cube is edge^3
Let the smaller cube = e^3 = 1e
Larger cube = 4e^3 = 64e
The ratio would be 64:1
Answer:
89-198345-19850 that's to the the tenth
7square root of 3 there’s no symbol
