See below

$S A = 96$ $SA=96$ sq in.

Explanation:

$V = s^{3}$ $V=s^3$
$64 = s^{3}$ $64=s^3$
find the cubic root of each side
$\sqrt[3]{64} = s$ $root(3)64=s$
$4 = s$ $4=s" "$ so the side of the cube is 4 cu in.

The surface area of a cube is $S A = n A$ $" "SA=nA$
where $S A$ $SA$ is surface area, $n$ $n$ is the number of faces, and $A$ $A$ is the area of one face.

Te area of one face ( $A$ $A$ ) is $s^{2}$ $s^2" "$ so $A = 16$ $A=16$
$n = 6$ $n=6$

$S A = 6 \cdot 16 = 96$ $SA=6*16=96$
