Question

Orthographic projection of a cube is shown as :

• A. (i)
• B. (ii)
• C. (iii)
• D. (iv)

Hint:

Orthographic projections use 2D square views for a cube—typically front, top, and side. Multiple squares = correct projection!

Answer 1

The Correct Option is B

Orthographic projection is a technique used in engineering drawing to represent 3D objects in two dimensions using multiple 2D views.
The cube, being a symmetric solid, has equal faces, and its orthographic projections appear as squares from all directions—front, top, and side.
- Option (ii) shows two square views stacked vertically, representing top and front views correctly.
- Option (iv) shows three square views arranged as front, top, and side—all of which are correct representations of a cube in orthographic projection.
- Option (i) and (iii) depict isometric or pictorial views where 3D depth is visible—these are not orthographic projections.
Hence, the correct multiple selections are (B) and (D).
