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.
