Answering the question required the basic idea of areas of  plane/compound shapes. Many candidates could not identify the various faces of the prism hence could not solve the problem. The prism had 3 rectangular faces and 2 triangular faces. Candidates were to find the areas of the respective faces and add them together to get the required surface area = 2408cm2. Some candidates viewed the prism as having only 4 faces and hence could not get the correct answer.
