The question figure shows the 3D view of an object. Identify the correct top view.
Show Hint
Imagine looking straight down: the cylinder at the front shows as a narrow rectangle, the front block as a large rectangle and the raised rear block as a strip split into a flat part and a sloping part.
The object is a block with a flat top, a taller wedge-shaped block behind it whose top has a flat part and a sloping part, and a cylinder sticking out of the front face. Looking from above with the cylinder towards the bottom of the view: 1. The cylinder is seen as a narrow rectangle at the bottom, attached to the front block. 2. The front block gives the large rectangle in the middle. 3. The raised rear wedge gives a strip at the top. Its flat top and its sloping face meet along a line, so this strip is divided into two parts by a vertical line. Only option (1) has the narrow rectangle at the bottom and a top strip divided into two parts by a vertical line. Option (2) does not show the division of the wedge, option (3) puts the divided strip next to the cylinder at the front instead of at the back, and option (4) again has no division at the back. Answer: (1) the first top view (strip at the top divided into two parts, narrow rectangle at the bottom)
