Question

The length, width and height of a cuboid are 3, 2 and 1 unit along x,y and z axes. If one corner is the origin, then cannot be a corner of the cuboid.

• A. (3,0,1)
• B. (0,2,0)
• C. (0,0,0)
• D. (0,2,1)
• E. (3,0,0)
• F. (0,1,0)

Answer 1

The correct option is F (0,1,0)

One of the corners is the origin, and the lengths along x,y and z axes are 3 units, 2 units and 1 unit respectively. Hence, the x-coordinate can be either 3 or 0, y-coordinate can be 2 or 0 and the z-coordinate can be 1 or 0. Hence, (0,1,0) cannot be a corner of the cuboid as its y-coordinate is 2.
