Answer:
352sq.cm.
Step-by-step explanation:
There are a total of 5 cubes.
To find the surface area of the corner cubes, we have have to multiply 4^2 * 5 because one of the surface is attached to the other cube's surface. 16*5 is one cube's surface area, so times 2 gives us 160.
To find the surface area of the cubes in the middle, we have to multiply 4^2 * 4 because two of their sides are attached to other cube's side. So 16*3 = 64 and we have 3 of them so it's 192.
Now adding all the surface area, 192 + 160, we get a total of 352 for the surface area of that figure.
