Directions : The 3 - D problem figure shows the view of an object. Identify, its correct top view, from amongst the answer figures.
Show Hint
The object is a block with an L-shaped tall wall (left and back), a lower pocket floor in the middle and a front-right wall with a small slot at its right end.
The object has a tall wall along the left and a tall wall along the back, enclosing a lower rectangular pocket whose floor is a single plane. On the right there is a tall wall with a rectangular slot cut into its right end. In the top view the outline is a rectangle. The left wall is about one fifth of the width, the back wall about one third of the height, the pocket takes about half the width, and the right wall takes the remaining three tenths of the width. The slot appears as a small rectangle touching the right edge, lying roughly in the middle of the height. Figure (1) shows the pocket cut into two extra strips, which the object does not have. Figure (2) has a pocket that is too small and a slot that is too long. Figure (4) has a very narrow slot and a pocket that is too narrow. Figure (3) shows the single pocket with the correct width and the slot in the right place. Answer: (3) the third figure
