Q: A solid figure is given followed by a problem. Each surface of the solid figure (marked with 1, 2, 3, 4, 5, 6, etc.) corresponds to a specific surface of the given problem. Your task is to find out how it corresponds. Figure 1 1 refers to the surface A B H E 2 refers to the surface A B C D 3 refers to the surface C D F G 4 refers to the surface B C G H 5 refers to the surface A D F E 6 refers to the surface E F G H Figure 2 (key figure with points A, B, C, D, E, F, G, H numbered 1-8) If surfaces B and D in figure 1 correspond to surfaces 1 and 3 respectively in key figure 2, then the points marked as 5 in figure 1 correspond to which point in the key figure 2?
