For this case we have by definition, that the surface area of a cube is given by:

SA = 6l ^ 2

Where:

l: It's the side of the cube

We have as data, according to the figure, that:

l = 8ft

Substituting in the figure:

$SA = 6 (8) ^ 2\\SA = 6 * 64\\SA = 384 \ ft ^ 2$

Thus, the surface area of the cube is
$384 \ ft ^ 2$

Answer:

$384 \ ft ^ 2$
