Question

The 3D figure shows the view of an object. Identify the correct top view, from amongst the answer figure.

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Work out the outline of the base (a rectangle with the front-right corner cut away), then place the tall left wall and the thin tall right wall at the back.

Answer 1

The Correct Option is C

The object is a base slab with two upright walls. In the plan (view from the top, with the front at the bottom of the figure):
(i) The front of the slab is stepped: the front-right corner is cut away, so the outline of the plan is a rectangle with the bottom-right corner removed.
(ii) The left wall is a tall block along the left edge, running from the front towards the back for a little more than half of the depth. In plan it is a narrow rectangle at the bottom left.
(iii) The right wall is a thin block at the back right, running along the back edge for about half of the width. In plan it is a long thin rectangle at the top right.
Option 3 shows exactly this: an outline with the bottom-right corner cut away, a narrow rectangle at the bottom left and a long thin rectangle at the top right.
Option 1 has no cut-away corner. Option 2 shows a full-depth strip on the left. Option 4 shows a full-width strip along the top. None of them agrees with the object.
Answer: (3) Figure shown in option 3
