Answer:
36 square units
Step-by-step explanation:
well the surface area is:
let's say that the surface of a cube is 1 squared units
so in the figure we have the faces:
up (blue)
down (not seen)
front (green)
back (not seen)
left (yellow)
right (not seen)
so the are of the blue is 6 and also is the down area
the area of the front is 6 and also is the back area
the area of the left is 6 and also the right area
so we have
[tex]S_a = 6+6+6+6+6+6\\\\S_a = 6*6\\\\S_a = 36[/tex]square units
