In general, answering a question which asks you to calculate the surface area of a shape means that you have to find the area of ALL the faces of that shape and add them up. In your case, you've got a rectangular prism (which in other words, is a cuboid.) Cubes and cuboids have 6 faces so you have to calculate the area of all 6 faces and then add them up.
It is really very difficult to fully explain this in written words over the internet without any pictures or without being face-to-face explaining this to you since attempting a question like this requires a lot of visualising.
I can however, just give you the answer.
6 x 4 = 24cm2
6 x 4 = 24cm2
6 x 12 = 72cm2
6 x 12 = 72cm2
4 x 12 = 48cm2
4 x 12 = 48cm2 +
----------------------
= 288cm2
Essentially what I did was calculate the area of each of the 6 faces based on the measurements you gave me and then added them up.
NOTE: Remember, that what we are calculating is AREA and because the measurements were in centimetres, the units were cm2
Hope that helps.

A rectangular prism with a length of 11m, width of 8m and height of 3m has a volume of 264m3

To determine the surface area of a rectangular prism, the two sides, adjacent sides, and ends of the prism must be added up. To do this, the sides are the product of the prism's length and height, the adjacent sides the width and height, and the ends the product of the length and width.
The area does not provide sufficient information to determine the length, width and height.
