Find the ratio of surface area to volume for a cube with a volume of 64 in^3.

Reiny,
I have now done quite a few of these type of questions for you.
Show me that you can do this easy one.

Piggy,
v = s^3
64 = s^3
s = 4 in
SA = 6s^2
= 6 x 4^2
= 1024 in^2
Now I know v = 64 in^3 & SA = 1024 in^3
The ratio is 1024/64 = 16:1
is it right????

Reiny,
6 x 4^2
= 6x16
= 96 , not 1024
so ratio is 96/64 = 3/2

Piggy,
thanks
