To find the answer, we first need to understand what a rectangular prism is formed by rectangles(as shown in the picture).
We can then find the surface area by finding the area of these rectangles
The area of the base and top:
16x4x2
=128m^2
The area of the side surfaces(note they are formed by two shapes of rectangles):
4x16x2 + 4x4x2
=128+32
=160m^2
In total:
128+32+128
=288
Therefore the answer is 288m^2
Hope it helps!
