Question

The 3D problem figure shows the view of an object. Identify its appropriate top view from the answer figures.

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Look down on the object: the tall wall appears as a long strip with a lower short end part, then the low block, the sloping wedge and the right-hand block appear as separate regions.

Answer 1

The Correct Option is A

Looking from above, the tall wall that runs along one side appears as a strip across the top of the plan. Its far end is a short, lower part, so the strip is divided into a long part and a short part, with the long part on the left.
Below the strip are three regions: the low block on the left (a tall rectangle), the narrow sloping wedge in the middle (a narrow rectangle ending where the wedge meets the floor) and the right-hand block, whose edge steps inward near the bottom because of the notch at its front.
Option (1) shows exactly this. Option (4) puts the short part of the strip on the wrong side; option (3) omits the edges between the left block, the wedge and the right block; option (2) shows the short part of the wall set back and an extra division in the right block, which the object does not have.
Answer: (1) the first top view
