The area of the surface that needs to be iced is 480 m².
Step-by-step explanation:
A cake has the same shape as a rectangular prism. A rectangular prism has six faces. The first one is formed by the length and the width, the second is formed by the length and the height and the third is formed by the width and the height, each of these faces is mirrored, so the surface area for the cake is:
surface area = 2*width*height + 2*width*length + 2*length*height
surface area = 2*12*4 + 2*12*12 + 2*12*4
surface area = 96 + 288 + 96 = 480 m²
The area of the surface that needs to be iced is 480 m².
