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 staircase-like solid: a sloping block on the left with a small block on its back end, a middle step and a lower step on the right, plus a floor in front of the sloping block.
The object has a left block with a sloping top, with a small notched block on the back end of its upper part; to its right a middle step and then a lower step; in front of the middle step there is a floor area shorter than the steps behind it. In the top view the shape is a large rectangle with a rectangular piece missing at the bottom right. The back row consists of the left strip, the middle step and the right step; the front row consists of the lower part of the left strip and the front floor, which is narrower than the middle step above it. The left strip is divided into two parts only on the left (where the sloping block meets the small back block), and the boundary between the back row and the front row lies lower than that division. Figure (4) shows exactly this: the divided left strip, a front floor narrower than the middle step and a long back row. The other figures differ in where the dividing lines run or in how wide the front floor is. Answer: (4) the fourth figure
