For this case we have by definition, that the surface area of a cube is given by:
[tex]SA = 6l ^ 2[/tex]
Where:
l: It's the side of the cube
We have as data, according to the figure, that:
[tex]l = 8ft[/tex]
Substituting in the figure:
[tex]SA = 6 (8) ^ 2\\SA = 6 * 64\\SA = 384 \ ft ^ 2[/tex]
Thus, the surface area of the cube is [tex]384 \ ft ^ 2[/tex]
Answer:
[tex]384 \ ft ^ 2[/tex]
